Title: | On the Topological Semigroup of Equational Classes of Finite Functions Under Composition |
Issue Date: | 2017 |
Abstract: | We consider the set of equational classes of finite functions endowed with the operation of class composition. Thus defined, this set gains a semigroup structure. This paper is a contribution to the understanding of this semigroup. We present several interesting properties of this semigroup. In particular, we show that it constitutes a topological semigroup that is profinite and we provide a description of its regular elements in the Boolean case. |
