Eta-Invariants for Parameter-Dependent Operators Associated with an Action of a Discrete Group
K. N. Zhuikov, A. Yu. Savin Peoples' Friendship University of Russia, Moscow
Abstract:
$\eta$-invariants for a class of parameter-dependent nonlocal operators associated with an isometric action of a discrete group of polynomial growth on a smooth closed manifold are studied. The $\eta$-invariant is defined as the regularization of the winding number. The formula for the variation of the $\eta$-invariant when the operator changes is obtained. The results are based on the study of asymptotic expansions of traces of parameter-dependent nonlocal operators.
Keywords:
elliptic operator, parameter-dependent operator, nonlocal operator, $\eta$-invariant.
