On semigroups of endomorphisms of a chain with restricted range
Let X be a finite or infinite chain and let O(X) be the monoid of all endomorphisms of X. In
this paper, we describe the largest regular subsemigroup of O(X) and Green's relations on …

The rank of the semigroup of all order-preserving transformations on a finite fence
VH Fernandes, J Koppitz, T Musunthia - Bulletin of the Malaysian …, 2019 - Springer
A zig-zag (or fence) order is a special partial order on a (finite) set. In this paper, we consider
the semigroup TF _ n TF n of all order-preserving transformations on an n-element zig-zag …
