Number Theory meets Differential Equations: Using Homotopy Continuation to Compute Shabat Polynomials
A Belyĭ pair \bigl( S,\, z(w) \bigr) is a compact, connected Riemann surface S together with a rational function z \colon S \to \mathbb{P}^1(\mathbb{C}) which has at most three critical values \bigl\{ 0,\, 1,\, \infty \bigr\}. The preimage z^{-1}\bigl( \bigr) \subseteq S \hookrightarrow \mathbb{R}^3 is a bipartite graph called a Dessin d'Enfant. When S = \mathbb{P}^1(\mathbb{C}) […]

Hilbert basis for conical semigroups and indecomposable elements (Lenny Fukshansky, CMC)
The unique minimal generating set for a semigroup of lattice points in an n-dimensional polyhedral cone is called its Hilbert basis. In the case when the cone is spanned by lattice points, this Hilbert basis is finite, however its cardinality can be much larger than n. Nevertheless, a conjecture of Sebö states that each point […]
Claremont Topology Seminar: Sam Nelson (CMC)
Speaker: Sam Nelson (CMC) Title: Permutation Jones Polynomials Abstract: The Jones Polynomial is an important invariant of knots with applications in physics, quantum computation and more. In this talk I will introduce a family of generalizations of the Jones polynomial associated to permutations of finite sets and discuss their properties. _______ We especially welcome all […]

CCMS Colloquium: The Stochastic Logistic Map: Theory and Applications — Kimberly Ayers (CSU San Marcos)
Flyer for Kim's talk. Abstract: The logistic map is one of the most famous examples in dynamical systems. Originally introduced as a simple model of population growth, it exhibits a surprisingly rich range of behavior: as a single parameter varies, stable equilibria give way to periodic orbits and eventually to chaos. But in real populations, […]
