NHCU-HEP-94-13 Classical N=2 W-superalgebras From Superpseudodifferential Operators

چکیده
We study the supersymmetric Gelfand-Dickey algebras associated with the superpseu-dodifferential operators of positive as well as negative leading order. We show that, upon the usual constraint, these algebras contain the N=2 super Virasoro algebra as a subal-gebra when the leading order is odd. The decompositions of the coefficient functions into N=1 primary fields are then obtained by covariantizing the superpseudodifferential operators. We discuss the problem of identifying N = 2 supermultiplets and work out a couple of supermultiplets by explicit computations.

On Contractions of Classical Basic Superalgebras
We define a class of orthosymplectic osp(m; j|2n;ω) and unitary sl(m; j|n; ǫ) superalgebras which may be obtained from osp(m|2n) and sl(m|n) by contractions and analytic continuations in a similar way as the special linear, orthogonal and the symplectic Cayley-Klein algebras are obtained from the corresponding classical ones. Casimir operators of Cayley-Klein superalgebras are obtained from the...
متن کاملAn Analog of the Classical Invariant Theory for Lie Superlagebras
Let V be a finite-dimensional superspace over C and g a simple (or a “close” to simple) matrix Lie superalgebra, i.e., a Lie subsuperalgebra in gl(V ). Under the classical invariant theory for g we mean the description of g-invariant elements of the algebra A p,q k,l = S . (V k ⊕Π(V ) ⊕ V ∗p ⊕Π(V )). We give such description for gl(V ), sl(V ) and osp(V ) and their “odd” analogs: q(V ), sq(V );...
متن کاملAlgebraic generalization of quantum statistics
Generalized quantum statistics such as para-Bose and para-Fermi statistics are related to the basic classical Lie superalgebras B(0|n) and Bn. We give a quite general definition of “a generalized quantum statistics associated to a Lie superalgebra G”. This definition is closely related to a certain Z-grading of G. The generalized quantum statistics is determined by a set of root vectors (the cr...
متن کاملDeforming the Lie Superalgebra of Contact Vector Fields on S 1 | 1 inside the Lie Superalgebra of Superpseudodifferential operators on S 1 | 1
We classify nontrivial deformations of the standard embedding of the Lie superalgebra K(1) of contact vector fields on the (1,1)-dimensional supercircle into the Lie super-algebra of superpseudodifferential operators on the supercircle. This approach leads to the deformations of the central charge induced on K(1) by the canonical central extension of SΨDO.

We consider the compatibility conditions for a N-particle D-dimensional Wigner quantum oscillator. These conditions can be rewritten as certain triple relations involving anticommutators, so it is natural to look for solutions in terms of Lie superalgebras. In the recent classification of " generalized quantum statistics " for the basic classical Lie superalgebras [1], each such statistics is c...
