Title: Generalized homomorphisms and KK with extra structure

Authors: Joachim Cuntz, James Gabe
(Submitted on 10 Apr 2024)
Abstract: We develop the approach via quasihomomorphisms and the universal algebra $qA$ to Kasparov's $KK$-theory, so as to cover versions of $KK$ such as $KK^{nuc}$, $KK^G$ and ideal related $KK$-theory.
