Abstract

We study the semigroup Icfλ of injective partial cofinite selfmaps of an infinite cardinal λ. We show that Icfλ is a bisimple inverse semigroup and each chain of idempotents in Icfλ is contained in a bicyclic subsemigroup of Icfλ , we describe the Green relations on Icfλ and we prove that every non-trivial congruence on Icfλ is a group congruence. Also, we describe the structure of the quotient semigroup Icfλ /σ, where σ is the least group congruence on Icfλ.

Keywords: bicyclic semigroup; semigroup of bijective partial transformations; congruence; symmetric group; group congruence; semidirect product
