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…

In a classical special case, thethe tensor product of graded abelian groups leads to a model for…
