D\'evissage for periodic cyclic homology of complete intersections

K-Theory and Homology 2024-08-21 v3 Algebraic Geometry

Abstract

We prove that the d\'evissage property holds for periodic cyclic homology for a local complete intersection embedding into a smooth scheme. As a consequence, we show that the complexified topological Chern character maps for the bounded derived category and singularity category of a local complete intersection are isomorphisms, proving new cases of the Lattice Conjecture in noncommutative Hodge theory.
