We first prove a strong convergence theorem of Mann's type for a commutative family of continuous linear operators in a Banach space by using strongly regular sequences of means on commutative ...
We show that the join of a variety of semigroups and the variety of all commutative semigroups is not finitely based, provided some weak conditions. Journal Information This monthly journal, begun in ...
Affine semigroups are finitely generated submonoids of Euclidean space that naturally arise in algebraic geometry and commutative algebra, while monomial curves are defined by parametrisations whose ...
