Actions of Fusion Category on Algebras
Fusion categories are rich mathematical objects that generalize finite groups and their representation categories. What does it mean for a fusion category to act on an algebra? Do these actions generalize group actions on algebras? In this talk, we will define an action of a fusion category on an algebra and show how it relates to group actions on algebras. Then, as an application of this theory, we will apply our results to study actions of fusion categories on path algebras.

Computing stable homology representations of graph configuration spaces
Configuration spaces parametrize distinct labelled points in a topological space. They have rich geometry and have been studied extensively. In 2011, Church and Farb introduce the idea of representation stability for a sequence of representations $V_n$ of groups $G_n$. Configuration spaces lend themselves naturally to this framework. In this talk, we will focus on configuration spaces of families of graphs with a fixed number of points and discuss their stability behavior, where $V_n$ is taken to be the rational homology and $G_n$ the automorphism group of the underlying graph. We carry out extensive computational work to determine the stable homology representations for several families with 2 points, such as the star graphs, the complete graphs, and the complete bipartite graphs. We also give combinatorial interpretations to some stable subrepresentations. This is joint work with Eric Ramos. Our paper can be found on the arXiv with handle 2606.13813.

Qualitative Properties of Multilayered Structure-Fluid Interaction Coupled PDE Dynamics
We consider a composite structure (multilayered) and fluid interaction PDE system which arises in multi-physics problems, and particularly in biofluidic applications related to the mammalian blood transportation process. The PDE system under consideration consists of the interactive coupling of 3D Stokes flow and 3D elastic dynamics which gives rise to an additional 2D elastic equation on the boundary interface between these 3D PDE systems. We first show the existence-uniqueness properties of the coupled system by means of a nonstandard mixed variational formulation and linear semigroup theory. In the second part, we analyze the long-time behavior of the solutions to such FSI coupled system and address the issue of asymptotic decay of this solution to the zero state via a frequency domain approach.
