摘要
证明了非零特征域上导代数DAn 的Krull维数等于n,并讨论了DAn 模的外乘积,以及外乘积的滤子与分次结构、Gelfand-Kirillov 维数和重数。
The Krull dimension of the derivative algebra DA n over a field of nonzero characteristic is proved to be n. The external product of DA n modules is defined. The filtration and graded structure, the Gelfand Kirillov dimensions and multiplicities of the external products of DA n modules are also investigated.
