Artin-Tate motivic sheaves with finite coefficients over an algebraic variety

Leonid Positselski

We propose a construction of a tensor exact category F_X^m of Artin-Tate motivic sheaves with finite coefficients Z/m over an algebraic variety X (over a field K of characteristic…

Galois cohomology of a number field is Koszul

Leonid Positselski

We prove that the Milnor ring of any (one-dimensional) local or global field K modulo a prime number l is a Koszul algebra over Z/l. Under mild assumptions that are only needed in…

The algebra of closed forms in a disk is Koszul

Leonid Positselski

We prove that the algebra of closed differential forms in an (algebraic, formal, or analytic) disk with logarithmic singularities along several coordinate hyperplanes is (both nont…

Mixed Artin-Tate motives with finite coefficients

Leonid Positselski

The goal of this paper is to give an explicit description of the triangulated categories of Tate and Artin-Tate motives with finite coefficients Z/m over a field K containing a pri…
