Reading Group: Bott & Tu
This semester, I'd like to organize a reading group focusing on Bott and Tu's lovely book, Differential Forms in Algebraic Topology. The goal is to learn about cohomology from the point of view of differential geometry. My hope is to get to material on characteristic classes.
