Abstracts of Current Research:- Fourier transforms for Hopf algebras: All finite dimensional and some infinite dimensional Hopf algebras give rise to integrals which define in turn Fourier Transorms for these Hopf algebras. We study these transforms and the convolution product induced by them and further study Quantum Fourier transforms F. We apply F to give a purely algebraic proof of the Verlinde formula for semisimple factorizable Hopf algebras.
- Characters and a Verlinde-type formula for Symmetric Hopf algebras: We study certain aspects of finite dimensional non-semisimple symmetric Hopf algebras H and their duals. We focus on the set of characters of projective H-modules and prove that under cetain conditions there exists a Steinberg-like character . We also prove a Verlinde-type formula for a certain well-known ideal of the center of H.
