#### An introduction to CAT(0) cube complexes

###### Marissa Miller (UIUC)

Abstract: In this talk, I will introduce the notion of a CAT(k) metric spaces, which are spaces that have geometry comparable to complete simply connected surfaces of constant curvature k. We will specifically focus on CAT(0) spaces and will explore CAT(0) cube complexes in some detail, looking at various examples of these complexes and their relationships to questions in geometric group theory. Please email basilio3 (at) illinois (dot) edu for Zoom details.

#### Introduction to Geometric Group Theory and Hyperbolicity

###### Marissa Miller (UIUC)

Abstract: Geometric group theory is an area of math that relates groups to metric spaces via their actions on these spaces. Studying the geometric and topological properties of the metric spaces on which groups act can give information about the algebraic properties of a group, as well as the geometric properties of a group (a notion which I will make precise in the talk). I will discuss some of the basic ideas in geometric group theory, and I will provide some examples of theorems in geometric group theory using Gromov-hyperbolic groups.
