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 from an algebraic Lie algebra , such that has no nontrivial semi-invariants in and is a polynomial algebra.
As an application, we solve the derived isomorphism problem of enveloping algebras for the above class of Lie algebras.

一类李代数的Veldkamp定理的推广
Veldkamp的一个经典定理描述了特征p中一个半简单代数群的Lie代数的一个包络代数的中心。我们将此结果推广到一类李式代数,其性质为归约模 来自代数李代数 ,这样 在中没有非平凡的半不变量 和 是多项式代数。
作为一种应用,我们解决了上述一类李代数的包络代数的导出同构问题。
