EHT - Equivariant homotopy theory in context

A transfer system is a graph on a lattice satisfying certain restriction and composition properties. They were first studied on the lattice of subgroups of a finite group in order to examine equivariant homotopy commutativity, which then unlocked a wealth of links to other topics. On a finite lattice, transfer systems can be used to classify different homotopy theories using model categories. The talk will involve plenty of examples.
