Simplicial Complexes, Configuration Spaces, and “Chromatic” Invariants (Andrew Cooper, NC State)
Roberts North 104, CMC 320 E. 9th St., Claremont, CA, United StatesGiven a space $X$, the configuration space $F(X,n)$ is the space of possible ways to place $n$ points on $X$, so that no two occupy the same position. But what if we allow some of the points to coincide? The natural way to encode the allowed coincidences is as a simplicial complex $S$. I will […]

Claremont Math Weekend 2019
Pryne Auditorium, Galileo Hall, Harvey Mudd College 301 Platt Blvd., Claremont, CA, United StatesOn Saturday January 26th, Claremont Math Faculty will present 30 minute talks on their research. The goal of these presentations is to expose students, both graduate and undergraduate, to various areas of mathematics and applications that Claremont mathematicians are researching. Faculty presenters will provide Claremont Colleges course titles and descriptions that are related to their […]

Discrete compressed sensing: lattices and frames (Josiah Park, Georgia Tech)
Millikan 2099, Pomona College 610 N. College Ave., Claremont, CA, United StatesLattice valued vector systems have taken an important role in packing, coding, cryptography, and signal processing problems. In compressed sensing, improvements in sparse recovery methods can be reached with an additional assumption that the signal of interest is lattice valued, as demonstrated by A. Flinth and G. Kutyniok. Equiangular tight frames are particular systems of […]

Mathematics: Pure, Applied, A Liberal Art ( Al Erisman, Seattle Pacific University)
Shanahan B460, Harvey Mudd College 301 Platt Blvd., Claremont, CA, United StatesFrom the view of a pure mathematician, those working in pure mathematics produce pure knowledge. Whether used or not, it has a great elegance and value in and of itself. […]

The Roger-Yang Arc Algebra (Helen Wong, CMC)
Roberts North 104, CMC 320 E. 9th St., Claremont, CA, United StatesBased on geometric considerations, J. Roger and T. Yang in 2014 defined a version of the Kauffman bracket skein algebra for punctured surfaces that includes arcs going from puncture to puncture. We'll provide a brief survey of known results about this arc algebra. In particular, I'd like to mention a recent algebraic result whose […]

GEMS Workshop: Graph Theory, Part I with Professor Michael Orrison, from Harvey Mudd College
Shanahan 1480, Harvey Mudd College 301 Platt Blvd., Claremont, CA, United StatesTOPIC: Graph Theory, Part I On the surface, graphs seem to be some of the simplest objects you might encounter in mathematics. After all, they are made up of just […]

Estimating the physical location of Twitter users with the von Mises-Fisher distribution (Mike Izbicki, UC Riverside)
Emmy Noether Room, Millikan 1021, Pomona College 610 N. College Ave., Claremont, CaliforniaApproximately 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. […]

Lattices from group frames and vertex transitive graphs (Lenny Fukshansky, CMC)
Millikan 2099, Pomona College 610 N. College Ave., Claremont, CA, United StatesTight frames in Euclidean spaces are widely used convenient generalizations of orthonormal bases. 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, […]

Algebraic and Polyhedral Perspectives on Combinatorial Neural Codes (Robert Davis, Harvey Mudd)
Shanahan B460, Harvey Mudd College 301 Platt Blvd., Claremont, CA, United StatesIn the 1970s, James O’Keefe and his team observed that certain neurons in the brain, called place cells, spike in their firing rates when the animal is in a particular […]

Community structure in networks: the effect of communities on a preferential attachment model and epidemic spreading (Emily Fischer, Cornell)
Emmy Noether Room, Millikan 1021, Pomona College 610 N. College Ave., Claremont, CaliforniaOnline social networks and other networks of interest are known to exhibit community structure, where a community is defined to be a highly interconnected group of nodes with possibly shared […]
