Fix a finite group G and an algebraically closed field F of characteristic p. For an FG-module M, the complexity of M is the rate of growth of a minimal projective resolution of M. The rank varieties introduced by Carlson are used as a tool to determine complexities in a more computational way. In this talk, I will introduce some basic properties of rank varieties and complexities and then review some known results on complexities of modules for symmetric groups.
