Student Homotopy Theory Seminar

Algebraic topology solved the geometric problem of cobordism. Roughly speaking, two closed manifolds are cobordant if their disjoint union is the boundary of some other manifold. In this talk, I will explain how to set up the theory and the classical computational results done by Thom, Milnor, etc. Of particular importance is the theory of complex cobordism, which leads to further new mathematics. I will introduce both equivariant and chromatic developments, including some of the work recently done. Speaker(s): Yunze Lu (University of Michigan)
