Abstract
Let be a finite chain with elements , and let be the semigroup of all injective orientation-preserving partial transformations of . In this paper, for any nonempty subset of , we consider the subsemigroup of of all transformations with range contained in . We describe the Green's relations and study the regularity of . Moreover, we calculate the rank of and determine when two semigroups of this type are isomorphic.
