| 1. | In the second section , we give all the ring congruences on a commutative regular semiring s and show that from the lattice of all full , closed , ideal subsemirings of s to the lattice of all the ring conruences on 5 , there is a lattice isomorphism
首先给出一个交换正则半环上的所有环同余，证明了此半环的所有满的、闭的、理想子半环所形成的格与此半环的环同余格同构。 |
