主要研究有限域上零维理想的准素分解问题,时文[1]的所提到的方法和理想商环不变子空阃的基元素的可分性进行讨论,并给出了判定的充分必要条件。
This paper mainly studies the problem of primary decomposition of zero- dimensional ideals over finite fields.For the method which is given in [1],we do some work in an element of the invariant subspace of the quotient algebra, and give a necessary and sufficient condition to judge whether the dement is separable or not.
