The purpose of this paper is to extend the invariance of domain theorem to a large class of countably 1-ฮณ -contractive maps, by using homotopy theory and degree theory for countably 1-ฮณ -contractive maps.

## Abstract We present a generalization of Koplienkoโ€“Neidhardt trace formula for pairs of Hilbert space operators (__T__ , __V__ ) with __T__ contractive and __V__ unitary such that __T__ โ€“ __V__ is a Hilbertโ€“Schmidt operator. We extend the result to pairs of contractions and then, via Cayley trans
