Abstract

In this article, we find a family SLn,m, in any arbitrary dimensions, of cohomologically rigid solvable Lie superalgebras with nilradical the model filiform Lie superalgebra Ln,m. Moreover, we exhibit a family of cohomologically rigid solvable Lie superalgebras with nilradical the model nilpotent Lie superalgebra of generic characteristic sequence. Both cases correspond to solvable Lie superalgebras of maximal dimension for a given nilradical. Contrariwise, we will show that the family of Lie superalgebras SLn,m can be deformed if defined over a field of odd characteristic.

具有模型丝状和模型幂零零基的上同调刚性可解李超代数

摘要

在这篇文章中,我们找到了一个家庭 n,, 在任意维度上,具有 nilradical 模型丝状李超代数的上同调刚性可解李超代数 n,.此外,我们展示了一系列上同调刚性可解李超代数,其具有 nilradical 泛型特征序列的模型幂零李超代数。两种情况都对应于给定 nilradical 的最大维数的可解李超代数。反之,我们将证明李超代数族n, 如果在奇特性场上定义,则可以变形。
