Growth of regulators in finite abelian coverings

Thang T Q Lê

Algebraic & Geometric Topology 13 (2013) 2383–2404
Abstract

We show that the regulator, which is the difference between the homology torsion and the combinatorial Ray–Singer torsion, of finite abelian coverings of a fixed complex has sub-exponential growth rate.

Keywords
regulator, torsion homology, abelian covering
