Abstract

The symmetric inverse semigroup I(X)I(X) on a set XX is the collection of all partial bijections between subsets of XX with composition as the algebraic operation. We study a minimal Hausdorff inverse semigroup topologies on I(X)I(X). When XX is countable, we show some Polish semigroup topologies on I(X)I(X).
