Presentations for monoids of endomorphisms of a star graph
Vitor H. Fernandes, Jörg Koppitz, Tiwadee Musunthia
In this paper, we consider the monoids of all endomorphisms, of all weak endomorphisms, of all strong endomorphisms and of all strong weak endomorphisms of a star graph with a fini…
Presentations for monoids of partial endomorphisms of a star graph

The maximal subsemigroups of the ideals on a monoid of partial injections
Apatsara Sareeto, Jörg Koppitz
In the present paper, a submonoid of the well studied monoid of all order-preserving partial injections on an -element chain is studied. The set of all par…
