A tribute to Euler
Freeberg Forum, LC 62, Kravis Center, CMCAmong the greatest of mathematicians is Leonhard Euler (1707-1783), whose insight, industry, and ingenuity are unsurpassed in the long history of mathematics. In this talk we sketch Euler’s life, describe the quantity and quality of his mathematical output, and discuss a few of his discoveries from the realms of number theory, geometry, analysis, and combinatorics. […]
Pre-Colloquium Non-Colloquium Party
Millikan Courtyard, Pomona College 610 N. College Ave., Claremont, CA, United StatesThe traditional year-opening social event for the Claremont Colleges Mathematics Community will be held in the Millikan Courtyard. Spouses, partners, and family are welcome. Professors Ali Nadim (CGU) and Blerta Shtylla (POM), co-chairs, hope to see everyone there for refreshments, and other pleasant pursuits.
Applied math organizational meeting
Emmy Noether Room, Millikan 1021, Pomona College 610 N. College Ave., Claremont, CaliforniaWe will have an organizational meeting for the applied math seminar today. Anyone who is interested in suggesting speakers and/or organizing applied math seminar is welcome to come.
Small representations of integers by integral quadratic form (Lenny Fukshansky, CMC)
Millikan 2099, Pomona College 610 N. College Ave., Claremont, CA, United StatesGiven an isotropic integral quadratic form which assumes a value t, we investigate the distribution of integer points at which this value is assumed. Building on the previous work about the distribution of small-height zeros of quadratic forms, we produce bounds on height of points outside of some algebraic sets in a quadratic space at […]
An Algebra of Arcs and Knots on a Surface (Helen Wong, CMC)
Argue Auditorium, Pomona College 610 N. College Ave., Claremont, CA, United StatesThe end of the previous century saw radical changes to three-dimensional topology, which arose from two completely different approaches. One breakthrough came from Bill Thurston's introduction of hyperbolic geometry into the field. The second one came from the Vaughn Jones’s discovery of a new "quantum" invariant for knots that brought in insight and techniques from […]
Diffusion, Social Networks, and Logic (Pavel Naumov, CMC)
Emmy Noether Room, Millikan 1021, Pomona College 610 N. College Ave., Claremont, CaliforniaOnce a new commercial product, technology, political opinion, or social norm is adopted by a few people, these few often put peer pressure on others to consider adopting it as well. Those who adopt next put even more pressure on the rest of the population. This cascading “epidemic” effect is often called diffusion in social […]
Inversions for reduced words (Sami Assaf, USC)
Millikan 2099, Pomona College 610 N. College Ave., Claremont, CA, United StatesThe number of inversions of a permutation is an important statistic that arises in many contexts, including as the minimum number of simple transpositions needed to express the permutation and, equivalently, as the rank function for weak Bruhat order on the symmetric group. In this talk, I’ll describe an analogous statistic on the reduced expressions […]

Quandle coloring quivers (Sam Nelson, CMC)
Millikan 2099, Pomona College 610 N. College Ave., Claremont, CA, United StatesGiven a finite quandle $X$, a set $S \subset \mathrm{Hom}(X,X)$ of quandle endomoprhisms, and an oriented knot or link $L$, we construct a quiver-valued invariant of oriented knots and links. This quiver categorifies the quandle counting invariant in the most literal sense and can be used to define many enhancements of the counting invariant. This […]
Snow Business: Scientific Computing in the Movies and Beyond (Joseph Teran, UCLA)
Argue Auditorium, Pomona College 610 N. College Ave., Claremont, CA, United StatesNew applications of scientific computing for solid and fluid mechanics problems include simulation of virtual materials in movie visual effects and virtual surgery. Both disciplines demand physically realistic dynamics for materials like water, smoke, fire, and soft tissues. New algorithms are required for each area. Teran will speak about the simulation techniques required in these fields and […]
Reaction-Diffusion Equations under Perturbations of the Domain (Professor Jose Arrieta, Universidad Complutense de Madrid, Spain)
Shanahan 3465, Harvey Mudd College 301 Platt Blvd., Claremont, CA, United StatesWe analyze the behavior of the asymptotic dynamics of dissipative reaction-diffusion equations with Neumann boundary conditions when the domain where the equation is posed undergoes certain perturbation. We will focus on the behavior of the stationary solutions, their local unstable manifolds and the attractors. We will consider "regular" perturbations of the domain, that is, perturbations […]
