摘要:

利用了一个适当环面的权空间分解完全确定了从有限维特殊奇Hamiltonian模李超代数偶部到广义Witt超代数偶部的导子空间, 进而给出了相应的低维上同调空间的维数公式.

关键词: 权空间分解, 导子, 低维上同调群

Abstract:

Derivation spaces for even parts of finite-dimensional special odd Hamiltonian superalgebras into even parts of generalized Witt superalgebras are completely determined by means of weight space decompositions with respect to suitable tori. Moreover, the corresponding dimension formulas of low dimensional cohomology groups are determined.

Key words: Weight space decompositions, Derivations, Low dimensional cohomology groups
