Hopf algebras blend algebraic and coalgebraic structures to generalise the symmetry frameworks of groups, Lie algebras and algebraic groups. Initially emerging in algebraic topology for the study of ...

Hopf algebras constitute a central framework in modern algebra, merging structures from both algebra and coalgebra with an antipode map that renders them amenable to duality considerations. These ...

Scholarly Interests: Hopf algebras, deformations and extensions; Algebraic & geometric aspects of multiparameter spectral theory and Matrix algebras & matrix groups. On Bimeasurings, (with M. Mastnak) ...
