Covering space theory for graphs and surfaces, as an introduction to algebraic topology and its links to group theory.
This week-long class from Mathcamp 2019 covers (pun intended) covering space theory for graphs and surfaces, and is meant as an introduction to algebraic topology and its connection to group theory.
The prerequisites are group theory and minimal exposure to topology or analysis.
