设是一个复有限维半单李代数,是的任意sl(2)-子代数。本文证明了Penkov和Zuckerman提出的一个猜想:第一个导出的Zuckerman函子提供了一个厚抛物范畴的截断与容许(,)-模范畴的截断之间的等价性。后者截断范畴由容许的(,)-模与足够大的极小型。我们构造了一个显式函子逆Zuckerman函子在此设置。作为推论,我们得到了截断的容许(,)-模范畴的归纳完备化的整体内射维数的一个估计。
Letbe a complex finite-dimensional semisimple Lie algebra andbe any sl(2)-subalgebra of. In this paper we prove an earlier conjecture by Penkov and Zuckerman claiming that the first derived Zuckerman functor provides an equivalence between a truncation of a thick parabolic categoryforand a truncation of the category of admissible (,)-modules. This latter truncated category consists of admissible (,)-modules with sufficiently large minimal-type. We construct an explicit functor inverse to the Zuckerman functor in this setting. As a corollary we obtain an estimate for the global injective dimension of the inductive completion of the truncated category of admissible (,)-modules.
