What Kinds of Invariants Are Used to Classify Spaces and Their Symmetries?

Speaker: Sylvain Cappell

Location: Warren Weaver Hall 1302

Date: Friday, February 5, 2010, 1 p.m.

Synopsis:

We introduce kinds of invariants used to study and classify: 1) manifolds (in 3 levels of structure - differentiable, piecewise differentiable and topological); 2) more generally, varieties and their singularities; 3) the symmetries of all these, i.e., transformation groups which act on them.
