The binary quasiorder on semigroups

Taras Banakh, Olena Hryniv

Given two elements $x, y$ of a semigroup $X$ we write $x ≲ y$ if for every homomorphism $χ : X \to {0, 1}$ we have $χ (x) \leq χ (y)$ . The quasiorder $≲$ is called the $bina r y$ …

Embedding topological semigroups into the hyperspaces over topological groups

Taras Banakh, Olena Hryniv

We study algebraic and topological properties of subsemigroups of the hyperspace exp(G) of non-empty compact subsets of a topological group G endowed with the Vietoris topology and…

Characterizing compact Clifford semigroups that embed into convolution and functor-semigroups

Taras Banakh, Matija Cencelj, Olena Hryniv +1

We study algebraic and topological properties of the convolution semigroups of probability measures on a topological groups and show that a compact Clifford topological semigroup $…
