A class of finite-by-cocommutative Hopf algebras
Nicolás Andruskiewitsch, Sonia Natale, Blas Torrecillas
We present a rich source of Hopf algebras starting from a cofinite central extension of a Noetherian Hopf algebra and a subgroup of the algebraic group of characters of the central…
Quadratic algebras associated with exterior 3-forms
Michel Dubois-Violette, Blas Torrecillas
This paper is devoted to the study of the quadratic algebras with relations generated by superpotentials which are exterior 3-forms. Such an algebra is regular if and only if it is…
On sovereign, balanced and ribbon quasi-Hopf algebras
Daniel Bulacu, Blas Torrecillas
We introduce the notions of sovereign, spherical and balanced quasi-Hopf algebra. We investigate the connections between these, as well as their connections with the class of pivot…
Frobenius and separable functors for the category of entwined modules over cowreaths, I: General theory
D. Bulacu, S. Caenepeel, B. Torrecillas
Entwined modules over cowreaths in a monoidal category are introduced. They can be identified to coalgebras in an appropriate monoidal category. It is investigated when such coalge…
An active attack on a distributed Group Key Exchange system
Mohamed Baouch, Juan Antonio López-Ramos, Reto Schnyder +1
In this work, we introduce an active attack on a Group Key Exchange protocol by Burmester and Desmedt. The attacker obtains a copy of the shared key, which is created in a collabor…
Quiver Bialgebras and Monoidal Categories
Hua-Lin Huang, Blas Torrecillas
We study the bialgebra structures on quiver coalgebras and the monoidal structures on the categories of locally nilpotent and locally finite quiver representations. It is shown tha…
