On conjugation in some transformation and Brauer-type semigroups
Ganna Kudryavtseva, Volodymyr Mazorchuk · Publicationes Mathematicae Debrecen · 2007
We give, in terms of (generalized) cyclic types, a criterion for two elements of T n , PT n , IS(N), B n , PB n and C n to be conjugate with respect to the conjugation defined as the transitive closure of the xy ∼ yx relation.
