Fusion, Crossing and Monodromy in Conformal Field Theory Based on Current Algebra with Fractional Level
J. L. Petersen, J. Rasmussen, M. Yu
Based on our earlier work on free field realizations of conformal blocks for conformal field theories with current algebra and with fractional level and spins, we discuss i…
Free field realization of SL(2) correlators for admissible representations, and hamiltonian reduction for correlators
J. L. Petersen, J. Rasmussen, M. Yu
Talk presented by J.L. Petersen at the 29th Symposium Ahrenshop, Buckow August 29-September 2, 1995. A presentation is given of the free field realization relevant to SL(2) WZW the…
Conformal blocks for admissible representations of current algebra
J. L. Petersen, J. Rasmussen, M. Yu
A review is presented of the recently obtained expressions for conformal blocks for {\it admissible} representations in current algebra based on the Wakimoto free field con…
Hamiltonian Reduction of -theories at the Level of Correlators
J. L. Petersen, J. Rasmussen, M. Yu
Since the work of Bershadsky and Ooguri and Feigin and Frenkel it is well known that correlators of current algebra for admissible representations should reduce to correlat…
Conformal Blocks for admissible representations in SL(2) current algebra
J. L. Petersen, J. Rasmussen, M. Yu
We show how to deal with screening charges involving fractional powers of free fields. This enables us to use the free field Wakimoto construction to obtain complete expressions fo…
A Hierarchy of Superstrings
Fiorenzo Bastianelli, Nobuyoshi Ohta, Jens Lyng Petersen
We construct a hierarchy of supersymmetric string theories by showing that the general N-extended superstrings may be viewed as a special class of the (N+1)-extended superstrings.…
