Transverse measures to infinite type laminations- Location- SC 1312

Alex Rassmusen- University of Utah

Geodesic laminations are crucial tools for studying mapping class groups and three-manifolds. However, little is understood about laminations on infinite type surfaces. In this talk, we consider the cone of transverse measures to a geodesic lamination on an infinite type surface. We show that this cone admits an explicit description as an inverse limit of finite-dimensional cones. We use this explicit description to illustrate exotic new behaviors exhibited by laminations on infinite type surfaces. This talk is based on joint work with Mladen Bestvina.

VandyGRAF Seminar Series- SC 6333 Physics Building- Title- Exotic Matter in Neutron Stars

Veronica Dexheimer, Kent State University

The high densities achieved in neutron stars and the high densities and temperatures achieved in neutron-star mergers create ideal testing grounds in which to learn about exotic matter, namely hyperons and deconfined quarks. The presence of exotic matter can strongly affect the interior of neutron stars, but cannot be directly observed. New electromagnetic and gravitational-wave constraints have been slowly constraining the dense QCD equation of state, allowing us to learn important information about the strong interaction. Nevertheless, strong constraints on dense and hot matter depend on (a) the not yet observed post-merger period of gravitational-wave production from neutron-star mergers and (b) non-trivial comparisons with particle collision experimental data. In this talk, I discuss where we stand and what we expect to learn about dense matter in the near future.

MTSU/Vanderbilt Graph Theory and Combinatorics Seminar- On the global dynamics of population network models Location – KOM 205 at MTSU and SC 1432 at Vanderbilt

Dr. Yixiang Wu, Assistant Professor in the Department of Mathematical Sciences at MTSU

In this talk, I will discuss about some of our recent results on population network models. For single species models, we consider the monotonicity of the spectral bound of a class of matrices, which measure the growth rate of the population when the size is small; we study the distribution of resources that maximize the total population in stream environment. For two species competition models, I will present a result that classifies the global dynamics of the model under some assumptions on the network structure.
