It starts with the basic results of the subject and progresses towards a treatment of several advanced topics not commonly found in functional analysis textbooks, including Fredholm theory, form ...

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

Dynamics: Investigating the dynamics of semigroup and group actions is a powerful tool that can be used to analyse mathematical problems. Non-reversible dynamics describes the evolution of systems ...
