Veldkamp定理在一类李代数上的推广

A generalization of Veldkamp's theorem for a class of Lie algebras

Akaki Tikaradze

摘要:

Veldkamp的一个经典定理描述了半单代数群的李代数的包络代数的中心在特征$p.$中我们将这个结果推广到一类李代数,它们具有这样的性质:它们是由代数李代数$\mathfrak{g},$产生的模$p\gg 0$的约化,使得$\mathfrak{g}$在$Sym(\mathfrak{g})$中没有非平凡的半不变量,并且$Sym(\mathfrak{g})^{\mathfrak{g}}$是多项式代数。作为应用,我们解决了这类李代数的包络代数的导出同构问题。

英文摘要:

A classical theorem of Veldkamp describes the center of an enveloping algebra of a Lie algebra of a semi-simple algebraic group in characteristic $p.$ We generalize this result to a class of Lie algebras with a property that they arise as the reduction modulo $p\gg 0$ from an algebraic Lie algebra $\mathfrak{g},$ such that $\mathfrak{g}$ has no nontrivial semi-invariants in $Sym(\mathfrak{g})$ and $Sym(\mathfrak{g})^{\mathfrak{g}}$ is a polynomial algebra. As an application, we solve the derived isomorphism problem of enveloping algebras for the above class of Lie algebras.
