关于Kac-Moody代数和量子化包络代数的Bernstein-Gelfand-Gelfand分解

On the Bernstein-Gelfand-Gelfand resolution for Kac-Moody algebras and quantized enveloping algebras

I. Heckenberger, S. Kolb

摘要:

证明了任意Kac-Moody代数和单根集合的任意子集的Bernstein-Gelfand-Gelfand归结。此外,还建立了对称化Kac-Moody代数的Bernstein-Gelfand-Gelfand归结的量子群类似.对于固定复非零变形参数q的量子化包络代数,证明了对所有非单位单位根的q都是正合的.

英文摘要:

A Bernstein-Gelfand-Gelfand resolution for arbitrary Kac-Moody algebras and arbitrary subsets of the set of simple roots is proven. Moreover, quantum group analogs of the Bernstein-Gelfand-Gelfand resolution for symmetrizable Kac-Moody algebras are established. For quantized enveloping algebras with fixed complex nonzero deformation parameter q exactness is proven for all q which are not a root of unity.
