This page is intended for the students of my B3.2 Geometry of Surfaces class.
Here is where you may find the notes I've prepared for each class. If you're looking for solutions to the problem sheets, you're in the wrong place.
Notes on why the Euler characteristic is independent of the choice of cellular decomposition.
Notes on how we may make \( \mathcal{H} / \mathrm{PSL}(2, \mathbb{Z}) \) into a Riemann surface at the elliptic points.
