研究了李Poisson超代数的泛中心扩张问题.通过构造其泛中心扩张,得到了其存在泛覆盖的充要条件是李Poisson超代数是完全的,并对李Poisson超代数的自同构群及导子的提升给出了结果.
This paper is devoted to studying the universal central extensions of Lie Pois- son superalgebras. The authors develop the general theory of universal central extensions, obtaining that a Lie Poisson supera]gebra has a universal central extension if and only if it is perfect. The authors also give results on the lifting of automorphisms and derivations of Lie Poisson superalgebras.
