在[S]中,Kac和Kazhdan对可对称化Kac-Moody李代数G上Verma模M(-p)的不可约商L(-p)的特征公式给出了以下猜想:chL(-p)= e-”fl(1-c ')-~'~. 3 td(cc zl+0)本文的目的是证明当G是欧氏李代数时的猜想.此外,我们还能够确定在这种情况下M(-p)的Jantzen过滤。如果G是欧几里得李代数,则上述猜想可以重写为
In [S], Kac and Kazhdan gave the following conjecture on the character formula of the irreducible quotient L (-p) of the Verma module M (-p) over a symmetrizable Kac-Moody Lie algebra G: chL (-p)= e-” fl (1-c’)-~~~‘~. 3td (cc zl+ OThe purpose of this paper is to give a proof for the conjecture when G is a Euclidean Lie algebra. In addition, we were also able to determine the Jantzen filtration of M (-p) in this case. If G is a Euclidean Lie algebra, the above conjecture can be rewritten as
