Equivariant analytic torsion forms

Abstract

In this paper, we first construct infinitesimal equivariant analytic torsion forms for Kähler fibrations. We then compare them with Ma's equivariant analytic torsion forms, modulo $\partial$- and $\overline{\partial }$-exact forms, in terms of equivariant Bott--Chern currents and the $I$-genus. Our comparison formula extends that of Bismut and Goette to families.
