In [1], Borcherds defined generalized Kac-Moody (denoted by GKM for short) algebras and gave a character formula for lowest weight modules of these algebras. In this paper we give a character formula for lowest weight modules of GKM superalgebras. For any standard result about contragredient superal

✦ Synopsis
In this paper, we introduce the notion of crystal bases of Kac᎐Moody superalgebras. We prove the existence of the crystal bases for integrable modules following Kashiwara's grand loop argument and we also prove the tensor product rule for these bases. We simplify his argument without introducing the notion of the boson y Ž . structure on the U ᒄ . ᮊ 2001 Academic Press q q
The notion of Kac᎐Moody superalgebras is a generalization of that of Kac᎐Moody algebras. Naturally, we want to develop the theory of crystal

In the present paper we determine all the elements in the root lattices of symmetrizable Kac᎐Moody algebras whose reflections preserve the root systems. Also we discuss elements in the root lattices whose reflections preserve the root lattices.
We show that a set of monic polynomials in a free Lie superalgebra is a Grobner᎐Shirshov basis for a Lie superalgebra if and only if it is a Grobner᎐Shirshov basis for its universal enveloping algebra. We investigate the structure of Grobner᎐Shirshov bases for Kac᎐Moody superalgebras and give ëxplic
