About this document
Understanding Sheaves and Stalks by oscar is a document available to read on EtoBox.
This document provides an overview of sheaves and presheaves. It defines a presheaf as a contravariant functor from open sets of a topological space to modules. A presheaf is a sheaf if sections over open sets patch together uniquely. The sheafification of a presheaf is the sheaf with sections given by continuous functions of the presheaf
