一类无限维李代数的二上圈
2-cocycles on an Infinite-dimensional Lie Algebra
摘要
考虑了一类无限维李代数L的二上圈.通过计算,得到了此类李代数的所有的二上圈,从而确定了L的二上同调群.
In the paper, we consider 2-cocycles on an infinite-dimensional Lie algebra L. We obtain all of the 2-cocycles on this Lie algebra and further determine its second cohomology group.
