Semiflows on topological spaces: Chain transitivity and semigroups
, 2015 This paper studies semiflows on topological spaces. A concept of chain recurrence, based on families of coverings, is introduced and related to Morse decomposition.

, 2021 As the main result of this dissertation, we established an equivalence between the category of complete distributive inverse semigroups and that of etale localic groupoids by introducing a new class of morphisms for the former. This equivalence puts many

Extremal topologies on a semigroup
Topology and its Applications, 1991 Given a semigroup \((S,+)\) with discrete topology \(\tau_ d\), and given a set \({\mathcal A}\) of topologies on \(S\), an element \(\tau\) of \({\mathcal A}\) is said to be extremal (in \({\mathcal A})\) if (i) \(\tau\neq\tau_ d\) and (ii) if \(\tau\subseteq\tau'\in{\mathcal A}\) and \(\tau\neq\tau'\), then \(\tau'=\tau_ d\). The author shows that if
