Commuting degree for BCK-algebras

Rings and Algebras 2025-04-25 v1

Abstract

We discuss the following question: given a finite BCK-algebra, what is the probability that two randomly selected elements commute? We call this probability the \textit{commuting degree} of a BCK-algebra. In a previous paper, the author gave sharp upper and lower bounds for the commuting degree of a BCK-algebra with order nn. We expand on those results in this paper: we show that, for each n3n\geq 3, there is a BCK-algebra of order nn realizing each possible commuting degree and that the minimum commuting degree is achieved by a unique BCK-algebra of order nn Additionally, we show that every rational number in (0,1](0,1] is the commuting degree of some finite BCK-algebra.
