•  No Graduate Student Seminar

The Graduate Student Seminar is designed to give graduate students a low-pressure environment to gain experience presenting their work to their peers, and to practice public speaking skills more generally. For any questions, Contact Trevor Jess at tkjess@nmsu.edu or Susan Harding at susaneh@nmsu.edu.

When Powers Stay Linear: The Case of Simplicial Trees

Arvind Kumar, NMSU

We investigate when powers of facet ideals of simplicial trees retain linear resolutions. Extending the 2004 theorem of Herzog, Hibi, and Zheng beyond the quadratic case, we give a complete characterization of simplicial trees whose facet ideals have linear resolutions for all powers. We also examine the relationship between linear resolutions and linear quotients in this setting, identifying structural conditions under which these properties coincide for powers of facet ideals.

Exotic Phenomena in Dimension 4

Lisa Piccirillo, UT Austin

In favorable circumstances, topological 4-manifolds can be classified. In contrast, smooth 4-manifolds remain poorly understood. Several hard questions in 4-manifold topology boil down to asking whether there can be distinct smooth manifolds with the same topological type; such manifolds are called exotic. In this talk, I will discuss a few methods to produce exotic manifolds, and comment on how these methods might be adapted towards addressing some of these questions.

Topological 4-Manifolds With a Given Boundary

Anthony Conway, UT Austin

After briefly surveying the landscape of 4-dimensional topology (especially the difference between the smooth and topological categories), the talk will give an overview of known classifications of closed topological 4-manifolds, and conclude with recent classifications of topological 4-manifolds with boundary. Based on joint work with Daniel Kasprowski.
