Quantum algebra (Hopf algebras, quantum groups)
My field of research is the theory of Hopf algebras and quantum groups, including extensions of these concepts (quasi-Hopf algebras, quantum groupoids etc). In my research I have treated various aspects of the theory, such as: quasitriangular structures, ribbon and charmed elements, monoidal, braided and ribbon categories, links with Clifford algebras, octonions and Cayley-Dickson algebras, various kinds of crossed products (smash products and biproducts, double crossed products, diagonal crossed products, L-R-smash products, twisted tensor products of algebras), integrals and Maschke-type theorems, quantum traces and dimensions, actions and coactions, cleft extensions, the study of some classes of pointed Hopf algebras, (anti) Yetter-Drinfeld modules and Hopf (bi)modules, the quantum Yang-Baxter equation and the pentagonal equation, vertex groups, the Drinfeld double and the Heisenberg double, combinatorial and homological aspects, extensions, deformations etc.
