A Transversal Property for Permutation Groups Motivated by Partial Transformations

Group Theory 2019-11-07 v1

Abstract

In this paper we introduce the definition of (k,l)(k,l)-universal transversal property, which is a refinement of the definition of kk-universal transversal property, which in turn is a refinement of the classic definition of kk-homogeneity for permutation groups. In particular, a group possesses the (2,n)(2,n)-universal transversal property if and only if it is primitive; it possesses the (2,2)(2,2)-universal transversal property if and only if it is 22-homogeneous. Up to a few undecided cases, we give a classification of groups satisfying the (k,l)(k,l)-universal transversal property, for k3k\ge 3. Then we apply this result for studying regular semigroups of partial transformations.
