Quantum semigroups generated by locally compact semigroups

Marat A. Aukhadiev, Yulia N. Kuznetsova

Let $S$ be a subsemigroup of a second countable locally compact group $G$, such that $S^{-1}S=G$. We consider the $C^{\ast }$-algebra $C_{\delta }^{\ast }(S)$ generated by the operators of translation…
