In this talk, I will survey the known relationships between stable homotopy groups of Bousfield localizations of finite spectra and special values of L-functions. Given a p-local finite spectrum X,…

In I987 Nigel Hitchin proved that the moduli space of Higgs bundles on a smooth projective curve (of genus greater than equal to 2) has a natural symplectic structure. In…

Time: 17:00 (Israel Time) Location: On Zoom Abstract: The nerve functor from categories to simplicial sets allows to associate toany small category a homotopy type giving rise to a homotopy theory of smallcategories studied by Quillen, Thomason and Grothendieck. To…

The slice filtration is an equivariant analogue of the Postnikov tower and it is modeled on Voevodsky’s motivic filtration. I will begin by recalling the definition of slice filtration along…
