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 quantizing differentialâ€¦ (More)

We pursue the study of string interactions in the PP-wave background and show that the proposal of hep-th/0211188 can be extended to a full supersymmetric vertex. Then we compute some stringâ€¦ (More)

We report transovarial transmission of Gamboa virus (Bunyavirus) in Aedeomyia squamipennis, a tropical mosquito which is active and bloodfeeding throughout the year. Gamboa virus was isolated duringâ€¦ (More)

A review is presented of the recently obtained expressions for conformal blocks for admissible representations in SL(2) current algebra based on the Wakimoto free field construction. In thisâ€¦ (More)

Based on our earlier work on free field realizations of conformal blocks for conformal field theories with SL(2) current algebra and with fractional level and spins, we discuss in some detail theâ€¦ (More)

Since the work of Bershadsky and Ooguri and Feigin and Frenkel it is well known that correlators of SL(2) current algebra for admissible representations should reduce to correlators for conformalâ€¦ (More)

We give a simple proof that a particular class of N = 2 superstrings are equivalent to the N = 1 superstrings. This is achieved by constructing a similarity transformation which transforms the N = 2â€¦ (More)

We present explicit free field representations for the N = 4 doubly extended superconformal algebra, ÃƒÎ³. This algebra generalizes and contains all previous N = 4 superconformal algebras. We haveâ€¦ (More)
