Luogo: aula Vitali, ore 11:15
Abstract: Quillen’s celebrated stratification theorem provides a geometric description of the Zariski spectrum of the cohomology ring of any finite group with coefficients in a field in terms of information coming from its elementary abelian p-subgroups. The goal of this talk is give a gentle introduction to Quillen's theorem and discuss an extension of his result to the world of equivariant tensor-triangular geometry. This is joint work with Tobias Barthel, Natalia Castellana, Drew Heard and Niko Naumann.
