Suslin's moving lemma with modulus

Wataru Kai and Hiroyasu Miyazaki

Vol. 3 (2018), No. 1, 55–70
Abstract

The moving lemma of Suslin (also known as the generic equidimensionality theorem) states that a cycle on X × An meeting all faces properly can be moved so that it becomes equidimensional over An. This leads to an isomorphism of motivic Borel–Moore homology and higher Chow groups.

In this short paper we formulate and prove a variant of this. It leads to a modulus version of the isomorphism, in an appropriate pro setting.
