The sheaf property

Показать описание
Sheaf theory forms an important language for expressing local-global relationships that are found typically in geometry. In this video, we motivate and define the abstract notion of a sheaf by looking at the sheaf of continuous functions. The key is the sheaf property which we go through in detail.
This is the first video in a playlist on a "User's guide to coherent sheaves".

Dear Daniel Chan,
Thank you very much for these lectures. Your calm, almost soothing, way of presenting all these hard to grasp concepts is a real joy to experience!

Best regards from Holland!

Great video, it is the first time I'm able to understand the equalizer version of the sheaf condition.

A great introduction to sheaves! Also, I really like the format of mini-lectures :)
