Andew Belmonte, Pennsylvania State U, Do Your Fair Share! Evolutionary Games and the Tragedy of the Commons

April 20 | 4:00 pm - 5:00 pm EDT

Public goods games involve interactions between players or organisms who produce a commonly available good (cooperators) and those who consume it without producing (cheaters, defectors, freeloaders) - several instances are known to occur in nature and economics. The solution that…

Ying Zhou, Brandeis University, Tame Hereditary Algebras have finitely many m-Maximal Green Sequences

April 23 | 3:00 pm - 4:00 pm EDT

Keller introduced the concept of maximal green sequences. Brustle-Dupont-Perotin proved that tame quivers have finitely many maximal green sequences. We have generalized the result to m-maximal green sequences. This talk will include a gentle introduction to tame path algebras, their indecomposable modules, silting objects…

April 23 | 3:00 pm - 4:00 pm EDT

Speaker 1: Caprice Stanley Title: Markov Chain Mixing Time Abstract: Informally a Markov chain is a memoryless stochastic process and its mixing time is the time required for the chain to be near its stationary distribution. Depending on the context,…

Mario Ricchiuto, INRIA Bordeaux, On dispersive-like effects in channels with banks

April 24 | 3:00 pm - 4:00 pm EDT

The study of the propagation of undular bores in channels is relevant to many applications which go from the propagation of tsunami waves, to that of tidal bores/waves, to the propagation of strong waves in manmade channels due to hazards (e.g. dam breaking).…

Aliakbar Daemi, Simons Center for Geometry and Physics, Chern-Simons functional and the Homology Cobordism Group

April 25 | 10:40 am - 11:30 am EDT

The set of 3-manifolds with the same homology as the 3-dimensional sphere, modulo an equivalence relation called homology cobordance, forms a group. The additive structure of this group is given by taking connected sum. This group is called the homology cobordism group and…

Retirement Reception for Dr. Paur and Dr. Putcha

April 25 | 2:00 pm - 3:00 pm EDT

Daphne Klotsa, University of North Carolina at Chapel Hill, A touch of non-linearity at intermediate Reynolds numbers: where spheres “think” collectively and swim together

From crawling cells to orca whales, swimming in nature occurs at different scales. The study of swimming across length scales can shed light onto the biological functions of natural swimmers or inspire the design of artificial swimmers with applications ranging from…

Rosalie Bélanger-Rioux, Harvard University, Strategies for Supporting Diversity in Mathematics Departments

April 27 | 3:00 pm - 4:00 pm EDT

There are many reasons, moral and practical, why we need to diversify our mathematics departments — and more generally STEM departments and the workforce. But how do we go about it? A good starting point is to realize the various…

Emily Barnard, Northeastern University, Graph Associahedra and the Poset of Maximal Tubings

May 7 | 3:00 pm - 4:00 pm EDT

Given a graph G on n vertices, Postnikov defined a graph associahedron  P_G as an example of a generalized permutohedron, a polytope whose  normal fan coarsens the braid arrangement. Combinatorially, each face of  P_G corresponds to certain collections of compatible…
