完全幂等环
On completely idempotent rings
-
摘要: 首先得出整完全幂等环是域的结论,其次给出有单位元的完全幂等环的两个刻划,即有单位的完全幂等环是L-半单的,B-半单的,最后给出了一类有限完全幂等环的结构.Abstract: It is obtained that the integer completely idempotent rings are fields.Two characterization are gained that the completely idempotent rings with element are L-semisimple and B-semisimple.A class of finite completely idempotent rings is solved with |R|-p2.
