在[16]中,我们研究了第二Weyl代数的变形A α,β,并计算了它们的导子.本文确定了这些变形的半经典极限A α,β,并计算了它们的泊松导数。结果表明:第一Hochschild上同调群HH 1(A α,β)与第一Poisson上同调群HP 1(A α,β)同构.
Abstract In [16], we studied deformations A α, β of the second Weyl algebra and computed their derivations. In the present paper, we identify the semiclassical limits A α, β of these deformations and compute their Poisson derivations. Our results show that the first Hochschild cohomology group HH 1 (A α, β) is isomorphic to the first Poisson cohomology group HP 1 (A α, β).
