M-POLYSYMMETRICAL HYPERRINGS

open access: yesRatio Mathematica, 1997
In this paper a special case of canonical polysymmetrical hyperrings, the M-Polysymmetrical hyperrings, are studied and investigated in detail. Certain methods of their construction from rings are presented and a new class of hyperstructures, the M ...
