One of the basic ingredients of a quantum field theory (QFT) is an operator product expansion (OPE). I will explain what that is an how to formalize this notion in geometric terms using the Ran space (introduced in this context by Beilinson and Drinfeld). This leads to the theory of chiral algebras and factorization algebras.
