Regularity of the partial Baer-Levi semigroups with restricted range

Let \(Y\) be a fixed nonempty subset of an infinite set \(X\) and let \(q\) be an infinite cardinal such that \(q\leq|X|\). Let \(PS(X,Y,q)\) denote the semigroup of all partial injective transformations from \(X\) into \(Y\) for which the complement of its range has cardinality \(q\). Then \(PS(X,Y...
