About what?

A Grothendieck topology is a structure on a category that mimics the properties of open covers of topological spaces. These properties are particularly useful to define geometric structures in terms of local information, for example, an atlas on a manifold or a sheaf on an algebraic variety. The goal of this talk is to explain in simple terms how Grothendieck topologies and sheaves generalize familiar geometric objects.
