the balmer spectrum of a tensor triangulated category is a topological tool analogous to the usual spectrum of a commutative ring. it provides a universal theory of support, giving a categorical framework to (among others) the support varieties that have been used to great effect in modular representation theory. in this talk i will present an approach to the balmer spectrum of the stable module category of a hopf algebra using twisted tensor products and emphasizing examples. this will include an unpretentious introduction to twisted tensor products, the balmer spectrum, and the relevance of both in representation theory.
