Expanded Course Description

The aim of this course will be to introduce and study de Rham cohomology rings of open subsets of Euclidean space. Much of the course will focus on the powerful ways in which analysis and algebra can be employed to study topological spaces. Applications will include Brouwer’s Fixed Point Theorem, the Jordan–Brouwer Separation Theorem, and a topological interpretation of the chromatic polynomial of a graph.
