Reciprocity sheaves and logarithmic motives

Algebraic Geometry 2021-07-02 v1

Abstract

We connect two developments aiming at extending Voevodsky's theory of motives over a field in such a way to encompass non-A1\mathbf{A}^1-invariant phenomina. One is theory of reciprocity sheaves introduced by Kahn-Saito-Yamazaki. Another is theory of the triangulated category logDMeff\operatorname{\mathbf{logDM}}^{\operatorname{eff}} of logarithmic motives launched by Binda, Park and {\O}stv{\ae}r. We prove that the Nisnevich cohomology of reciprocity sheaves is representable in logDMeff\operatorname{\mathbf{logDM}}^{\operatorname{eff}}.
