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