Title :  The Picard group in equivariant homotopy theory via stable module categories

Abstract :  The Picard group of genuine G-spectra consists of those compact objects all of whose geometric fixed points are spheres. Work by tom Dieck - Petrie classifies these objects in terms of the dimensions at all conjugacy classes of subgroups. The question of which such ‘dimension functions’ can be realized is quite interesting. We present a new perspective on this question, based on a version of isotropy separation which plays well with compact objects.
