ON POLYGROUP HYPERRINGS AND REPRESENTATIONS OF POLYGROUPS
Davvaz, B.,Poursalavati, N.S. Korean Mathematical Society 1999 대한수학회지 Vol.36 No.6
In this paper we introduce matrix representations of polygroups over hyperrings and show such representations induce representations of the fundamental group over the corresponding fundamental ring. We also introduce the notion of a polygroup hyperring generalizing the notion of a group ring. We establish homo-morphisms among various polygroup hyperrings.
