A large class of algebras(possibly nonassociative)with group-coalgebraic structures,called quasigroup Hopf group-coalgebras,is introduced and studied.Quasigroup Hopf group-coalgebras provide a unifying framework for t...

Let G be a discrete group with a neutral element and H be a quasitriangular Hopf G-coalgebra over a field k. Then the relationship between G-grouplike elements and ribbon elements of H is considered. First, a list of ...

Let π be a group with a unit 1; H is a Hopf π- coalgebra and A is a right π-H-comodule algebra. First, the notion of a two-sided relative (A, H)-Hopf π-comodule is introduced; then it is obtained that Hom A H (...

The concept of weak Hopf group coalgebras is a natural generalization of the notions of both weak Hopf algebras(quantum groupoids) and Hopf group coalgebras.Let π be a group.The Morita context is considered in the ...

Oriented quantum algebras (coalgebras) are generalizations of quasitriangular Hopf algebras (coquasitriangular Hopf algebras) and account for regular isotopy invariants of oriented 1-1 tangles, oriented knots and ...
Let k be a commutative ring, C a projective k-coalgebra. The smash productsof entwining structure (A, C)_ψ are discussed. When the map ψ is a bijective, and C is a finitelygenerated k-module, a version of the Ulbric...
