Algebraic geometry 37: Singular points (replacement video))
Channel: Richard E Borcherds
Date: 2020-10-14

This lecture is part of an online algebraic geometry course, based on chapter I of "Algebraic geometry" by Hartshorne. It defines singular points and tangents spaces, and shows that the set of nonsingular points of a variety is open and dense.

This is a replacement for the original video, which had poor audio quality.
