On subhypergroups of fortified transposition hypergroups
Ch. G. Massouros, Gerasimos G. Massouros · AIP conference proceedings · 2013
Fortified Transposition Hypergroups appeared during the study of the theory of Formal Languages and Automata from the point of view of the hypercompositional structures theory. This paper studies the subhypergroups of these hypergroups and presents properties of their closed, symmetric, normal and reflexive subhypergroups.
