We present an explicit description of the ᒅ-support supp M of any irreducible ᒅ-locally finite ᒄ-module M, where ᒄ is any finite-dimensional Lie algebra and ᒅ is an arbitrary nilpotent Lie subalgebra of ᒄ. If ᒅ contains a Cartan subalgebra of the semi-simple part of ᒄ, we reformulate the description

✦ Synopsis
In this work a large number of irreducible representations with finite dimensional weight spaces are constructed for some toroidal Lie algebras. To accomplish this we develop a general theory of ޚ n -graded Lie algebras with polynomial multiplication. We construct modules by the standard inducing procedure and study their irreducible quotients using the vertex operator technics. ᮊ 1999 Academic Press U Both authors gratefully acknowledge support from the Natural Sciences and Engineering Research Council of Canada.
