介绍了李-莱因哈特代数扩展的 Chern-Weil 构造。这概括了微分几何中的经典 Chern-Weil 构造,并产生了 Lie-Rinehart 代数的任意扩展的特征类。给出了一些由奇点空间和叶状结构产生的例子,这些例子不能用经典的陈-魏伊结构来处理。
A Chern-Weil construction for extensions of Lie-Rinehart algebras is introduced. This generalizes the classical Chern-Weil construction in differential geometry and yields characteristic classes for arbitrary extensions of Lie-Rinehart algebras. Some examples arising from spaces with singularities and from foliations are given that cannot be treated by means of the classical Chern-Weil construction.
