β¦ Synopsis
We have obtained all the finite-dimensional umtary irreps of gl(m I n) and C(n), which also exhaust such irreps of all the basic classical Lie superalgebras. The lowest weights of such irreps are worked out explimtly. It is also shown that the contravariant and covariant tensor irreps of gl(m I n) are unitary irreps of type (I) and type (2) respectively, explaining the applicability of the Young diagram method to these two types of tensor irreps.

Presented here is a construction of certain bases of basic representations for classical affine Lie algebras. The starting point is a β«-ήβ¬grading α s α q α q α y1 0 1 of a classical Lie algebra α and the corresponding decomposition α s α q α q ΛΛα»Ή 1 0 α of the affine Lie algebra α. By using a genera
The main result of this paper is a classification of finite-dimensional representa-Ε½ . tions of the Lie superalgebras sl m, 1 of supertraceless endomorphisms of the Ε½ < . vector superspace of dimension m 1 . The classification extends to the so-called Ε½ . singly atypical blocks of the Lie superalgeb
Let G = osp(2, 2n) be the classical Lie superalgebra of type C of rank n + 1. Let Ξ» be a partition with Ξ» 1 n. Then Ξ» labels a finite-dimensional irreducible G-module, V (Ξ»). We describe the character of V (Ξ») in terms of tableaux. This tableaux description of characters enable us to decompose T = f
