We survey some known nice presentations of several monoids of partial transformations on
a finite chain: we consider the monoids of all order preserving partial transformations, of all …

Let ℐ n be the symmetric inverse semigroup on X n={1, 2,…, n}, and let 𝒟𝒫 n and 𝒪𝒟𝒫 n be
its subsemigroups of partial isometries and of order-preserving partial isometries of X n …

The main subject of this paper is the description of the congruences on certain monoids of
transformations on a finite chain Xn with n elements. Namely, we consider the monoids ORn …

In this paper, we consider the monoids of all partial endomorphisms, of all partial weak
endomorphisms, of all injective partial endomorphisms, of all partial strong endomorphisms …

In this paper we consider various classes of monoids of transformations of a finite chain,
including those of transformations that preserve or reverse either the order or the orientation …

In this paper we consider the monoid $ DPC_n $ of all partial isometries of an $ n $-cycle
graph $ C_n $. We show that $ DPC_n $ is the submonoid of the monoid of all oriented …
