idempotent element是什么意思

用法例句

P is any prime ideal in R,E(P)is a set of all idempotent elements of P.

(3)R/PE(P)为准体,其中P为R的任意素理想,E(P)为P的所有幂等元素组成的集合。

Idempotency of linear combinations of three idempotent matrices;

3个幂等矩阵线性组合的幂等性

In this paper,author makes a study on the characteristics of idempotent ma- trix and involution matrix,and computes the number of idempotent matrices and involu- tion matrices over finite field.

本文研究了幂等阵和对合阵的特性,并计算出有限域上幂等阵和对合阵的个数。

If Ф preserves commutative zero-products and Ф(FP)■FФ(P) and Ф(P)≠0 for every rank one idempotent operator P∈A,Then it has one of the following forms:an algebraic isomorphism,a conjugate algebraic isomor-phism,an algebraic anti-isomorphism and a conjugate algebraic anti-isomorphism.

若Ф保交换零积并且对所有的一秩幂等算子P∈A都有Ф(FP)FФ(P)和成立。
