It is a special feature of a global spectrum that the geometric fixed points functor admits extra functoriality; this can be encoded into the category G of finite groups and conjugacy classes of epimorphisms. Using Morita theory, Schwede showed that the category of rational global spectra admits a simple algebraic model: the abelian category of G-presheaves of rational vector spaces. In this talk I will explain how this category relates to certain stability phenomena in representation theory, and show how to use this algebraic description to understand the tensor triangulated geometry of the rational global stable homotopy category. This is joint work with Neil Strickland.<\/p>\n","protected":false},"excerpt":{"rendered":" Recording of this Seminar is available in the following link. https:\/\/zoom.us\/rec\/share\/9_VXM7j-zUVJetaS82vWYIoaFLrkT6a81nRM_KVYnkxNgIMXryoDbsd6vavVObNZ Geometry & Topology Seminar Speaker: Luca Pol, University of Sheffield Topic: Rational global spectra and tt-geometry Place: This is an online seminar.
