Abstract. A functional identity is an identical relation in a ring that besides
arbitrary elements also involves functions which are considered as unknowns.
The goal is to find their forms, or, when this is not possible, to describe the
structure of the ring in question. Results on functional identities have turned
out to be applicable to various mathematical areas, particularly to nonassociative
algebra. The talk will give a brief overview of the theory of functional identities
and its applications.
Abstract. In this talk I will tell you the non-trivial Lie algebras who have complete
classifications of simple weight modules.
Abstract. For an irreducible module $P$ over the Weyl algebra $/K_n^+$ and an
irreducible module $M$ over $/gl_n$, using Shen's monomorphism we make $P/otimes M$
into a module over the Witt algebra $W_n^+$. We show that $P/otimes M$ is an irreducible
module over $W_n^+$ if and only if $M/not/cong V(/delta_r, r)$ for any $r/in /{0, 1,/cdots, n/}$。
In this paper, we obtain a necessary and sufficient condition for the tensor product
ofirreducible loop modules and irreducible integrable highestweight modules to be simple
for the untwisted affine Kac-Moody algebras. This tensor product problem was originally
studied by Chari and Pressley 28 years ago.
