Classification of Two Dimensional N=4 Superconformal Symmetries
Abbas Ali
Classification of N=4 superconformal symmetries in two dimensions is re-examined. It is proposed that apart from SU(2) and their Kac-Moody symmetry c…

Comment on 'Anyon in External Elecromagnetic Field: Hamiltonian and Lagrangian Formulation'
Abbas Ali, Avinash Khare
We point out that in a recent paper by Chaichian et al. (Phys. Rev.Lett71(1993)3405) Dirac quantization procedure is not properly followed as a result of which the resulting quantu…

Topological Kac-Moody Algebra and Wakimoto Representation
Abbas Ali, Alok Kumar
It is shown, using the Wakimoto representation, that the level zero SU(2) Kac-Moody conformal field theory is topological and can be obtained by twisting an N=2 superconformal theo…
