Title: Introduction to Yang-Baxter Homology
Abstract: Yang-Baxter operators have been used to construct link invariants such as Jones Polynomial, HOMFLYPT Polynomial, etc. In this talk, I will introduce Yang-Baxter homology recently discovered by Jozef Przytycki and Victoria Lebed. In particular, the theory is motivated from distributive homology and set-theoretical Yang-Baxter homology.
Roundtable Conversations with GW Undergraduates
Wednesday, 4/16/2014, 3:30pm - 11:59pm
In the Fall 2011 we started a series of roundtable conversations with our undergraduate students. These meetings are an opportunity for the students to share their thoughts on our courses, to make suggestions that could improve our teaching, and to meet fellow students in other math classes. It is our hope that conversations like these will create positive interactions between students and faculty, and will lead to enhanced learning experience for our students.
Optimal characterization of learnability

Legendrian links, monotonic simplification, and Jones' conjecture on braids
Tuesday, 4/8/2014, 9:30pm - 11:59pm

Border-Collision Bifurcations in A Piece-Wise Smooth Planar Dynamical System Associated with Cardiac Potential
Tuesday, 4/8/2014, 7:00pm - 11:59pm
Speaker: Irina Popovici, US Naval Academy
Abstract: The talk addresses the bifurcations of a two-dimensional non-linear dynamical system introduced by Kline and Baker to model cardiac rhythmic response to periodic stimulation. The dynamical behavior of this continuous (but only piece-wise smooth) model transitions from simple (a unique attracting cycle) to complicated (co-existence of stable cycles) as the stimulus period is decreased from large towards zero.
