The semigroup generated by the idempotents of a partition monoid
, 2012 We study the idempotent generated subsemigroup of the partition monoid. In the finite case this subsemigroup consists of the identity and all the singular partitions. In the infinite case, the subsemigroup is described in terms of certain parameters that

Transformation Semigroups with the Deformed Multiplication
, 2005 Pairwise non-isomorphic semigroups obtained from the finite inverse symmetric semigroup $\mathcal{IS}_n ,$ finite symmetric semigroup $\mathcal{T}_n$ and bicyclic semigroup by the deformed multiplication proposed by Ljapin are classified.

Defining relations for idempotent generators in finite partial transformation semigroups
, 2014 We give a presentation for the semigroup of all singular partial transformations on a finite set, in terms of the generating set consisting of all idempotent partial transformations of corank ...

On the syntactic transformation semigroup of a language generated by a finite biprefix code
, 1982 Let P be a finite biprefix code and let X=(Q, S) be the syntactic transformation semigroup (ts) of P+. We show that if e ϵ S is an idempotent, then the ts Xe = (Qe, eqe) consists of partial one to one maps.

Groupoids associated to semigroup actions
, 2015 23 pagesIn this paper, we consider topological semigroup actions on compact topological spaces. Under mild assumptions on the semigroup and the action, we construct a semi-direct product groupoid with a Haar system.

Completely regular semigroups as semigroups of partial transformations
Semigroup Forum, 1994 Let \(S\) be a completely regular semigroup. The (right) Schützenberger representation of \(S\) is the morphism \(\rho: S \to {\mathcal P\mathcal T}(S)\), where for \(a \in S\), \(\rho_ a\) denotes right translation by \(a\), restricted to the principal ideal \(S a S\) that it generates.
