Action Dimension of Simple Complexes of Groups Kevin Schreve University of Chicago NSF Dickson Instructor of Mathematics “The geometric dimension of a discrete group G is the minimal dimension of a model for the classifying space BG. The action dimension... Read More
Occupancy Patterns in a Small Pond Network Dr. Zoi Rapti University of Illinois, Urbana-Champaign Associate Professor of Mathematics “In this talk, we will use metapopulation theory, stochastic and spatially explicit simulations, and four years of data to attempt to understand... Read More
Hierarchies and Dehn Fillings for Relatively Hyperbolic Cubical Groups Eduard Einstein University of Illinois at Chicago Research Assistant Professor “Wise characterized virtually special cubical groups as groups that admit quasiconvex hierarchies terminating in finite groups. Given a relatively hyperbolic group... Read More
End Sums of Manifolds Jack Calcut Oberlin College Associate Professor of Mathematics “End summing is the analogue for open manifolds of the boundary sum operation. Though it has been used in several applications since the 1980s, it is less well... Read More
Modeling Cancer Treatment with Oncolytic Viruses Combined with Dendritic Cell Injections Dr. Joanna Wares University of Richmond Associate Professor of Mathematics “Oncolytic viruses kill tumor cells by selectively replicating inside of them until they lyse. Recently, OVs have been enhanced... Read More
Genera of Knots in the Complex Projective Plane Mr. Jake Pichelmeyer Kansas State University PhD Student (ABD) “Let K be a knot and M be a smooth, closed four-dimensional manifold. The M-genus of K (plural: genera) is the least genus... Read More
Bestvina-Brady Groups with Polynomial Dehn Functions Dr. Yu-Chan Chang University of Wisconsin-Madison Visiting Assistant Professor “Bestvina–Brady groups are subgroups of right-angled Artin groups, and they satisfy quartic Dehn functions. There are examples of Bestvina–Brady groups whose Dehn functions are linear,... Read More
Gini Shortfall: A Coherent Risk Measure Dr. Ricardas Zitikis Western University Professor of Statistical and Actuarial Sciences “For quite some time, the value-at-risk (VaR) was an appealing risk measure, and even an industry and regulatory standard for calculating risk capital... Read More
Residual Finiteness of Certain Three Generator Artin Groups Dr. Kasia Jankiewicz University of Chicago L.E. Dickson Instructor “Despite the simple looking presentation much is unknown about Artin groups. However, some questions can be answered in suitable classes of Artin groups.... Read More
Translation-like Actions of Nilpotent Groups Dr. Mark Pengitore Ohio State University Zassenhaus Assistant Professor “Whyte introduced translation-like actions of groups which as a geometric generalization of subgroup containment. He then proved a geometric reformulation of the von Neumann conjecture by... Read More
