 Title: M-Solid Subvarieties of some Varieties of Commutative Semigroups Authors: Koppitz, J. Keywords: HypersubstitutionsM-HyperidentityM-Solid Subvarieties of Semigroups Issue Date: 1997 Publisher: Institute of Mathematics and Informatics Bulgarian Academy of Sciences Citation: Serdica Mathematical Journal, Vol. 23, No 1, (1997), 25p-34p Abstract: The basic concepts are M -hyperidentities, where M is a monoid of hypersubstitutions. The set of all M -solid varieties of semigroups forms a complete sublattice of the lattice of all varieties of semigroups. We fix some specific varieties V of commutative semigroups and study the set of all M -solid subvarieties of V , in particular, if V is nilpotent.
