Gorenstein categories and universal coefficient theorems

Abstract content

One can frequently interpret universal coefficient theorems as computations of hom-sets in some triangulated category T via morphisms and extensions between certain cohomological functors. The relevant cohomological functors are obtained by restricting the hom-functors of T to a "suitably nice" subcategory C. I'll discuss joint work with Ivo Dell'Ambrogio and Jan Stovicek which explains when C is "suitably nice" in terms of Gorenstein homological algebra in the category of representations of C and gives criteria to recognise suitably nice subcategories.
