Screening Currents in Affine Current Algebra
J. Rasmussen
In this paper screening currents of the second kind are considered. They are constructed in any affine current algebra for directions corresponding to simple roots with multiplicit…
Free Field Realizations of 2D Current Algebras, Screening Currents and Primary Fields
J. L. Petersen, J. Rasmussen, M. Yu
In this paper we consider Wakimoto free field realizations of simple affine Lie algebras, a subject already much studied. We present three new sets of results. (i) Based on quantiz…
Applications of Free Fields in 2D Current Algebra
J. Rasmussen
In this thesis steps are taken in the direction of formulating non-critical strings in the framework of the approach. A major part of the thesis is concerned with conformal f…
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…
