AI中文摘要:
在泊松正规元是泊松中心元的假设下,我们计算了单参数泊松幂零代数(简称PNA)的泊松导数和第一泊松上同调群。这尤其适用于与博特 - 萨梅森簇相关的某些泊松代数。
英文摘要:
We compute the Poisson derivations and the first Poisson cohomology group of uniparameter Poisson Nilpotent Algebras (PNA for short) under the hypothesis that Poisson-normal elements are Poisson-central. This applies in particular to certain Poisson algebras associated to Bott--Samelson varieties.
