But what if we allow some of the points to coincide? \nThe natural way to encode the allowed coincidences is as a simplicial complex $S$. I will describe how the configuration space $M(S\,X)$ obtained in this way gives rise to polynomial and homological invariants of $S$\, how those invariants are related to the cohomology ring $H^*(X)$\, and what this has to do with the topology of spaces of maps into $X$. \nI will also mention some potential applications of this structure to problems arising from international relations and economics. \nThis is joint work with Vin de Silva\, Radmila Sazdanovic\, and Robert J Carroll URL:https://colleges.claremont.edu/ccms/event/topology-seminar-1-24-2019-andrew-cooper-nc-state/ LOCATION:Roberts North 104\, CMC\, 320 E. 9th St.\, Claremont\, CA\, 91711\, United States CATEGORIES:Topology Seminar ORGANIZER;CN="Sam Nelson":MAILTO:snelson@cmc.edu END:VEVENT BEGIN:VEVENT DTSTART;TZID=America/Los_Angeles:20190126T093000 DTEND;TZID=America/Los_Angeles:20190126T173000 DTSTAMP:20260407T140943 CREATED:20190123T055731Z LAST-MODIFIED:20190123T224907Z UID:1131-1548495000-1548523800@colleges.claremont.edu SUMMARY:Claremont Math Weekend 2019 DESCRIPTION:On Saturday January 26th\, Claremont Math Faculty will present 30 minute talks on their research.

Kutyniok. Equiangular  tight  frames are  particular systems  of unit  vectors  with minimal  coherence\,  a measure of how well distributed the vectors are\, and have provable guarantees for recovery of sparse vectors in standard methods.  The determination whether real equiangular tight frames have integer span on a lattice has been given a characterization within two papers by A. Bottcher\, L. Fukshansky\, one with S. R. Garcia\, H. Maharaj and D. Needell.  Here the corresponding question is considered for the complex case and several families are demonstrated to have either integer span on a lattice or not.  In addition\, it is demonstrated that a real Parseval tight frame can have integer span on a lattice if and only if the inner products appearing in the system are rational.  (Collaboration with L.

Whether used or not\, it has a great elegance and value in and of itself. Those in applied mathematics simply pick up what has been done and use it in designing or building things. Number theory is often used to illustrate this\, where work done decades ago in pure mathematics is now central to encryption. \nHowever\, the relationship between pure and applied mathematics is a bit more complicated. New insights drawn from applications have been at the root of interesting new areas and questions in pure mathematics. Fourier analysis\, sparse matrix computation\, and graph theory all demonstrate this. \nSome have argued that\, whether pure or applied\, mathematics is not really needed by the average person. Alfred North Whitehead\, a Harvard mathematician and philosopher\, once stated\, “ideas [from mathematics] are of highly specialized application\, and rarely influence thought.” In other words\, mathematics is a specialized skill\, but not a liberal art. \nUsing examples from n-dimensional linear algebra\, I will show why I believe the areas of pure and applied mathematics are deeply tied\, and that this field does indeed influence thought in areas like understanding relationships and political discourse.

After all\, they are made up of just two kinds of parts\, vertices and edges\, and those parts fit together in simple ways. But appearances can be deceiving! In this series of two workshops\, we’ll explore several surprising facts about graphs. Along the way\, we’ll see how graphs arise in a variety of settings\, and how they give rise to many challenging but worthwhile problems. \nWHAT IS GEMS: \nThe Gateway to Exploring Mathematics program (GEMS) is a series of workshops that helps excite the interests and curiosity of young students in mathematics and science \nGEMS meets once a month on a Saturday morning from 10:00 AM to 12:00 PM \nGEMS is designed to reach 8th\, 9th and 10th grade students who have an interest in mathematics and science \nParticipants interact with excellent and award winning faculty\, staff\, students and alumni from each of the seven Claremont Colleges \nSPRING 2019 DATES: \nFebruary 2\, 2019 \nMarch 2\, 2019 \nApril 13\, 2019 \nREGISTRATION: \nTo register for our next event on February 2\, please click on the following link: \nhttps://tinyurl.com/GEMS2019Spring1 \nANY QUESTIONS: \nPlease contact our 2018-2019 GEMS coordinator\, Elsa Harris at Elsa.Harris@cgu.edu URL:https://colleges.claremont.edu/ccms/event/gems-workshop-graph-theory-part-i-with-professor-michael-orrison-from-harvey-mudd-college/ LOCATION:Shanahan 1480\, Harvey Mudd College\, 301 Platt Blvd.\, Claremont\, CA\, 91711\, United States CATEGORIES:GEMS ORGANIZER;CN="Elsa Harris":MAILTO:elsa.harris@cgu.edu END:VEVENT BEGIN:VEVENT DTSTART;TZID=America/Los_Angeles:20190204T161500 DTEND;TZID=America/Los_Angeles:20190204T171500 DTSTAMP:20260407T140943 CREATED:20181008T181051Z LAST-MODIFIED:20190117T015941Z UID:895-1549296900-1549300500@colleges.claremont.edu SUMMARY:Estimating the physical location of Twitter users with the von Mises-Fisher distribution (Mike Izbicki\, UC Riverside) DESCRIPTION:Approximately 500 million tweets are sent everyday.  Scientists monitor these tweets to predict the spread of disease\, better allocate social welfare services\, help first responders during natural disasters\, and many other important tasks.  A key step in each of these tasks is estimating the location the tweet was sent from.  In\nthis talk\, I discuss how to combine machine learning and the von Mises-Fisher distribution to estimate this location.  The von Mises-Fisher distribution is the spherical analog of the Gaussian distribution\, and this distribution lets us exploit the earth’s non-Euclidean geometry to improve estimation accuracy.

A particularly nice class of such frames is generated as orbits under irreducible actions of finite groups of orthogonal matrices: these are called irreducible group frames. Integer spans of rational irreducible group frames form Euclidean lattices with some very nice geometric properties\, called strongly eutactic lattices. We discuss this construction\, focusing on an especially interesting infinite family in arbitrarily large dimensions\, which comes from vertex transitive graphs. We demonstrate several examples of such lattices from graphs that exhibit some rather fascinating properties. This is joint work with D. Needell\, J. Park and J. Xin.

If a place cell is thought of as either “active” or “silent\,” then one may represent the co-firing patterns of place cells by a combinatorial neural code: a set of 0/1 vectors whose coordinates represent that status of distinct place cells. From the code\, we can try to reconstruct a geometric picture of the neural activity by sketching a disjoint union of simple closed curves in the plane. Ideally\, each curve corresponds to a unique place cell and the interiors of the curves are convex. However\, this is not always possible\, and identifying criteria which makes this possible is a difficult problem. \nIn this talk\, we will discuss approaches to the problem of representing combinatorial neural codes using convex sets. We will see how turning the codewords into polynomials can reveal hidden information about the code\, and how this naturally leads to examining properties of related polyhedra. In particular\, we will present progress on using polyhedra to identify representability of a code with circles in the plane.

However\, classic network models\, such as the preferential attachment model\, do not account for community structure. In this talk\, I will present the Community-Aware Preferential Attachment Model (CAPAM)\, which allows the user to specify community structure via edge probabilities. I will show that CAPAM retains desirable properties of the preferential attachment model\, namely a power-law degree distribution\, and further that the multivariate degree distribution is dependent upon the edge probabilities in an interesting way. I will show that community structure also plays a role in epidemic spreading processes. Under the SIS model\, the lifetime of a spreading process is constrained by the structure of the individual communities\, and the epidemic threshold is bounded closely around the threshold associated with the strongest community.

There is a sign that says that one of the two roads leads to prosperity and another to death. The agent must take the fork\, but she does not know which road leads where. Does the agent have a strategy to get to prosperity? On one hand\, since one of the roads leads to prosperity\, such a strategy clearly exists. On the other\, the agent does not know what the strategy is. \nIf a coalition of agents has a strategy\, it knows that it has a strategy\, and it also knows what this strategy is\, then we say that the coalition has a know-how strategy. In this talk I will discuss several of my recent papers on modal logics that describe the interplay between coalition knowledge\, strategies\, and know-how strategies.

Van Cott\, USF) DESCRIPTION:In 1968\, Milnor famously conjectured that the smooth 4-genus of the torus knot T(p\,q) is given by (p-1)(q-1)/2. This conjecture was first verified by Kronheimer and Mrowka in 1993 and has received several other proofs since then. In this talk\, we discuss a nonorientable analogue of this conjecture\, first formulated by Josh Batson. We prove the conjecture for infinite families of of torus knots\, using tools from knot Floer homology. We also connect the problem to the world of continued fractions\, which gives an alternative perspective on the problem. This is joint work with Stanislav Jabuka.

It juxtaposes the stories of two women trying to find their place in a white male-dominated academic world. The first is of historical Russian mathematician Sofia Kovalevskaya\, who was lauded as a pioneer for women in science but only after years of struggle for recognition. Her life’s journey is told through music and movement\, in both Russian and English. The second is of a fictional Asian-American woman\, known only as “Professor”\, trying to cope with the prejudice she faces in the present. As she teaches an introductory real analysis class\, she uses mathematical concepts to draw parallels to the race and gender conflicts she encounters in society today. \nSee https://www.corrineyap.com/uniformconvergence/ for more information about the play.

When a doctor takes your blood pressure\, the instrumentation may not be properly calibrated and the reading is subject to error. When completing an online Harry Potter Sorting Hat quiz\, you may accidentally click the wrong option for a specific question and find yourself in House Slytherin!. The effect of measurement error is sometimes insignificant\, but there are instances where ignored measurement error can be rather consequential. You definitely do not want your doctor to put you on a long-term medication for managing high BP due to an erroneous measurement! \nIn this talk\, I will discuss two problems frequently encountered when measurement error is present in sampled data. The first of these is known as density deconvolution\, which involves estimating the density function of the population of interest. When measurement error is present\, a density function estimated from the sample will have inflated variance\, and interesting population features may be obscured. The second problem relates to regression modeling when the predictor variable is subject to measurement error. Here\, when using the contaminated data to estimate the regression model\, parameter estimates will be biased unless measurement error is properly adjusted for. I will show how the empirical phase functions\, a transformation of the sample data to the complex plane\, can be used to find solutions to both of these problems. \nOh\, and don’t worry too much about your doctor unnecessarily prescribing blood pressure medication. She is well aware that measurement error exists\, and will re-take the measurement\, and also perform other tests before making a diagnosis.

(Jim Brown\, Occidental College) DESCRIPTION:Modular forms are ubiquitous in modern number theory.  For instance\, showing that elliptic curves are secretly modular forms was the key to the proof of Fermat’s Last Theorem.  In addition to number theory\, modular forms show up in diverse areas such as coding theory and particle physics.  Roughly speaking\, a modular form is a complex-valued function defined on the complex upper half-plane that satisfies a large number of symmetries.  A modular form has two invariants: weight and level.  If one fixes a weight and level\, the collection of modular forms of that weight and level form a finite-dimensional complex vector space.  One has a collection of operators on these spaces referred to as Hecke operators.  A natural question is if one takes two eigenforms of these operators and multiplies them\, when is the product still an eigenform?  It was shown in independent work by Duke and Ghate that there is a finite list of pairs of eigenforms whose product is again an eigenform.  In this talk we will report on the case when one replaces modular forms with the more general case of Siegel modular forms.  This is work that was partially conducted during an REU in summer 2018.  No prior familiarity with modular forms is assumed.

Indeed\, visual sequences of\npunctuation from different authors produce marvelously different (and\nvisually striking) sequences. Punctuation is a largely overlooked\nstylistic feature in “stylometry”\, the quantitative analysis of written\ntext. In this paper\, we examine punctuation sequences in a corpus of\nliterary documents and ask the following questions: Are the properties of\nsuch sequences a distinctive feature of different authors? Is it possible\nto distinguish literary genres based on their punctuation sequences? Do\nthe punctuation styles of authors evolve over time? Are we on to something\ninteresting in trying to do stylometry without words\, or are we full of\nsound and fury (signifying nothing)? \nFor more information\, see our recent preprint (joint work with Alexandra\nDarmon\, Marya Bazzi\, and Sam Howison):\nhttps://osf.io/preprints/socarxiv/2rzsg URL:https://colleges.claremont.edu/ccms/event/pull-out-all-the-stops-textual-analysis-via-punctuation-sequences-mason-porter-ucla/ LOCATION:Shanahan B460\, Harvey Mudd College\, 301 Platt Blvd.\, Claremont\, CA\, 91711\, United States CATEGORIES:Colloquium ORGANIZER;CN="Ali Nadim":MAILTO:ali.nadim@cgu.edu END:VEVENT BEGIN:VEVENT DTSTART;TZID=America/Los_Angeles:20190228T120000 DTEND;TZID=America/Los_Angeles:20190228T133000 DTSTAMP:20260407T140943 CREATED:20190127T185703Z LAST-MODIFIED:20190220T150331Z UID:1171-1551355200-1551360600@colleges.claremont.edu SUMMARY:Applying Quantum Representations of Mapping Class Groups (Wade Bloomquist\, UCSB) DESCRIPTION:One foundational pillar of low dimensional topology is the connection between link invariants and 3-manifold invariants.  One generalization of this has been given by Reshetikhin and Turaev to a surgery theory for colored ribbon graphs.  Then to complete the analogy rather than 3-manifold invariants we now have a 2+1 dimensional topology quantum field theory (TQFT).  For this talk we will only be focusing on one corner of a TQFT\, in particular the representations of mapping class groups which are afforded (called quantum representations).  We will first go through a brief construction of these representations\, focusing on how colored ribbon graphs give rise to a basis.  Then we will dive into some applications of these representations both in recovering classical topology and in a proposal for a topological quantum computing protocol.  A strong effort will be made to keep things relatively self contained with as many pictures as possible.

Such structure segments the domain into different regions with similar behavior according to a quantity. When we try to partition space-time into regions according to a Lagrangian quantity advected along with passive tracers\, such class of coherent structure is called the Lagrangian coherent structures (LCSs). Among many\, a simple definition of an LCS uses the finite-time Lyapunov exponent (FTLE). It measures the rate of separation between adjacent particles over a finite time interval with an infinitesimal perturbation in the initial location. In the talk\, we first present various Eulerian-based numerical methods which efficiently compute the flow maps of any continuous dynamical system and\, therefore\, the corresponding FTLE. Based on these techniques we developed\, we will also propose some other useful numerical tools for extracting important structures hidden in the system.

For example\, microfluidic devices carry very small volumes of liquid through channels and may be used to gain insight into many biological applications including drug delivery and development\, but mixing and pumping at this scale is difficult. Experimental work suggests that the flagella of bacteria may be used as motors in microfluidic devices\, and mathematical modeling can be used to further investigate this idea. Cilia self-organize forming a metachronal wave that propels the surrounding fluid. How this organization occurs is not well understood. Mathematical models can be used to study the role of hydrodynamic interactions in self-organization.

We present a generalization of this result that includes analogues for discrete cosine and discrete sine transform matrices as special cases.  This leads to a generalization of the Biro-Meshulam-Tao uncertainty principle to functions with symmetries that arise from certain group actions\, with some of the simplest examples being even and odd functions.  This new uncertainty principle gives a bound that is sharp and\, for some classes of functions\, stronger than that of Biro-Meshulam-Tao.
