Conformal Theories, BRST Formalism and Representations of the Lie Superalgebras
A. V. Voronin^{}, S. S. Horuzhy^{}
Abstract:
The results in the theory of representations of the Lie superalgebras are discussed which were obtained in the framework of a variant of the quantum BRST formalism developed by the authors. The central object of the study in this variant is the complete algebra $\mathcal A$ of the BRST symmetry which coincides with the Lie superalgebra $l(1,1)$. The set of these results presents a nearly complete description of the theory of representations of $\mathcal A$. For infinitedimensional representations, the criteria characterizing physical representations are established and a class of representations of $\mathcal A$ by unbounded operators in Krein spaces is constructed which is sufficiently large for all physical applications; all the problems concerning the operator domains are rigorously taken into account. For finitedimensional representations, the complete solution of the decomposition problem is presented. All the series of irreducible and indecomposable representations of $\mathcal A$ are explicitly described and all cases which do not admit any decomposition over these series are singled out and reduced to definite unsolvable algebraic problems.
