Consider the Stone–Čech compactification $βG$ of $G$ . We extend the operation on the set of composable elements $G^{(2)}$ of $G$ to the operation * on a subset $(βG)^{(2)}$ of $βG×βG$ such that the triple $(βG, (βG)^{(2)}$, *) is a compact right topological semigroupoid.}, number={4}, journal={Ukrains’kyi Matematychnyi Zhurnal}, author={Behrouzi, F.}, year={2015}, month={Apr.}, pages={456–466} }
