In this thesis ,we construct a new superalgebral called superalgebra with bracket corresponding to Lie superalgebra, and study the trivial homology,the universal central extension and lifting of automorphisms and derivations of it.
在第二章讨论了有括积超代数的上同调群理论,并且通过对有括积的超代数的平凡同调构造,最终得到一个与已知的短正合列相对应的五项正合列,从而得到有括积的超代数的泛中心扩张的核。
