Free Field Realization of Current Superalgebra Gl(m|n) K
We construct the free field representation of the affine currents, energy-momentum tensor and screening currents of the first kind of the current superalgebra gl(m|n)k uniformly for m = n and m 6= n. The energy-momentum tensor is given by a linear combination of two Sugawara tensors associated with the two independent quadratic Casimir elements of gl(m|n). PACS: 11.25.Hf; 02.20.Tw
متن کاملFree-field realization of the osp(2n|2n) current algebra
The osp(2n|2n) current algebra for a generic positive integer n at general level k is investigated. Its free-field representation and corresponding energy-momentum tensor are constructed. The associated screening currents of the first kind are also presented. PACS: 11.25.Hf

متن کاملRemarks on Free Field Realization
Free field representations of vertex algebra in SL(2,R)k/U(1) × U(1) WZNW model are constructed by considering a twisted version of the Bershadsky-Kutasov free field description of discrete states in the two-dimensional black hole CFT. These correspond to conjugate representations describing primary states in the model on SL(2,R)/U(1)× U(1). A particular evaluation of these leads to identities ...
