Title:“The more things change...”
Seminar:MASS Colloquium
Speaker:Chaim Goodman-Strauss, University of Arkansas
Abstract:
In two dimensions, there are three model geometries: the sphere, the Euclidean plane, and the hyperbolic plane. In each we can ask various kinds of combinatorial questions (“What are the possible discrete symmetry groups?” is a pretty good example). Although the spaces have pretty different properties, they’re not so different as they might seem. We’ll walk through several hands-on constructions, exploring the underlying topological, unifying perspective of orbifolds.
