Seminar

A Seiberg-Witten Floer stable homotopy type

Higher algebraic structures in algebra, topology and geometry

13 April 14:15 - 16:00

Matthew Stoffregen - Massachusetts Institute of Technology, MIT

We give a brief introduction to Floer homology and homotopy, from the Seiberg-Witten point of view. We will then discuss Manolescu's version of finite-dimensional approximation for rational homology spheres. We prove that a version of finite-dimensional approximation for the Seiberg-Witten equations associates equivariant spectra to a large class of three-manifolds. We give some applications to the the study of four-manifolds. This is joint work with Hirofumi Sasahira.
