isomporphism of rings

Motivated by the stability of ring homomorphisms,the ε-Hyers-Ulam stability of operator equations are introduced.

根据环同态的稳定性,引入了算子方程Ax=0的ε-Hyers-Ulam稳定性的概念。

The semiring congruence on a class of generalized regular semiring S was studied.

研究了一类广义正则半环S上的半环同余。

In this paper, we mainly discuss the relation between the ring congruence ρ on a strong distributive lattice of semirings S and the family of ring congruences ｛ρ_α｝_ α∈D on the family of semirings ｛S_α｝_ α∈D under some conditions.

主要讨论了在一定条件下半环的强分配格S上的环同余ρ与半环族{Sα}α∈D上的环同余族{ρα}α∈D之间的关系。
