چکیده
The fact that certain non-linear W2,s algebras can be linearized by the inclusion of a spin-1 current can provides a simple way to realize W2,s algebras from linear W1,2,s algebras. In this paper, we first construct the explicit field realizations of linear W1,2,s algebras with double scalar fields and spinor fields respectively. Then, after a basis inverting, the realizations of W2,s algebras are presented. The results show that all these realizations are Romans-type realizations.

Explicit description of twisted Wakimoto realizations of affine Lie algebras
In a vertex algebraic framework, we present an explicit description of the twisted Wakimoto realizations of the affine Lie algebras in correspondence with an arbitrary finite order automorphism and a compatible integral gradation of a complex simple Lie algebra. This yields generalized free field realizations of the twisted and untwisted affine Lie algebras in any gradation. The free field form...
متن کاملExtended Superconformal Algebras and Free Field Realizations from Hamiltonian Reduction
We develop the method of the hamiltonian reduction of affine Lie superal-gebras to obtain explicit and general expressions both for the classical and the quantum extended superconformal algebras. By performing the gauge transformation which connects the diagonal gauge with the Drinfeld-Sokolov gauge and considering the quantum corrections, we get generic expressions for the classical and quantu...
متن کاملOn explicit free field realizations of current algebras
We construct the explicit free field representations of the current algebras so(2n)k, so(2n + 1)k and sp(2n)k for a generic positive integer n and an arbitrary level k. The corresponding energy-momentum tensors and screening currents of the first kind are also given in terms of free fields. PACS: 11.25.Hf
متن کاملSuperconformal Algebras on the Boundary of AdS3
Motivated by recent progress on the correspondence between string theory on anti-de Sitter space and conformal field theory, we provide an explicit construction of an infinite dimensional class of superconformal algebras on the boundary of AdS3. These space-time algebras are N extended superconformal algebras of the kind obtainable by hamiltonian reduction of affine SL(2|N/2) current superalgeb...
متن کاملFree Field Realizations of Affine Current Superalgebras, Screening Currents and Primary Fields
In this paper free field realizations of affine current superalgebras are considered. Based on quantizing differential operator realizations of the corresponding basic Lie superalgebras, general and simple expressions for both the bosonic and the fermionic currents are provided. Screening currents of the first kind are also presented. Finally, explicit free field realizations of primary fields ...
