Algebraic Geometry over Heyting AlgebrasIn this article, we study the
algebraic geometry over Heyting
algebras and we investigate
Topological grading of semigroup C*-algebras of integers modulo
n. For these semigroups we study the structure of the reduced semigroup C*-
algebras which
Inductive Limits for Systems of Toeplitz Algebras© 2019, Pleiades Publishing, Ltd. By the Toeplitz
algebra we mean the reduced semigroup C*-
algebra Homogeneously simple associative algebrasWe prove that every finite-dimensional homogeneously simple associative
algebra over
Invariants of the action of a semisimple finite-dimensional Hopf algebra on special algebras of a finite-dimensional semisimple Hopf
algebra H on a special
algebra A, which is homomorphically
Operads and varieties of algebras defined by polylinear identitiesWe show that varieties of
algebras over abstract clones and over the corresponding operads
Structure of H-semiprime artinian algebrasLet H be a Hopf
algebra over a field. It is proved that every H-semiprime right artinian left H
Categoricity Spectra for Polymodal Algebras algebras (i.e., Boolean
algebras with distinguished modalities). We prove that the class of polymodal
