Nilpotent BCK-algebras
C. Matthew Evans
We recall the derived subalgebra of a BCK-algebra, and use this to define the derived ideal. Using the derived ideal, we show that the category of commutative BCK-algebras is a ref…

Commuting degree for BCK-algebras
C. Matthew Evans
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 d…
