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
We prove complete reducibility for an integrable module for an affine Lie algebra where the canonical central element acts non-trivially. We further prove that integrable modules does not exists for most of the superaffine Lie algebras where the center acts non-trivially.
It has been shown that up to degree shifts any integrable highest weight (or standard) module of level \(k\) for an affine Lie algebra \(g\) can be imbedded in the tensor product of \(k\) copies of level one integrable highest weight modules. When the affine Lie algebra \(g\) is of classical type th
