Gf. Birkenmeier et al., A CONNECTION BETWEEN WEAK REGULARITY AND THE SIMPLICITY OF PRIME FACTOR RINGS, Proceedings of the American Mathematical Society, 122(1), 1994, pp. 53-58
In this paper, we show that a reduced ring R is weakly regular (i.e.,
I2 = I for each one-sided ideal I of R) if and only if every prime ide
al is maximal. This result extends several well-known results. Moreove
r, we provide examples which indicate that further generalization of t
his result is limited.
