Title: Introduction to spectral sequences

Abstract:

Hey, I've got this homology that's hard to compute, so what should I do? Let's try breaking up the problem into smaller computations and piecing together the answer from the smaller answers. A spectral sequence is just what I need.

Spectral sequences are a computational tool that (vastly) generalizes long exact sequences. They have many applications in topology and algebra. The seminar will survey some of the theory and applications of spectral sequences. In this first talk, I will present some motivation, small examples, and the basics of spectral sequences.
