摘要
以半环S上的同态与同余为基础,定义了幂级数半环S[[x]]上的同态与同余,并在此基础上得出了一些重要结论。
S is a semi-ring, and is the semi-ring of formal power series （in the indeterminate ） over S. Based on the homomorphism and congruence on semi-ring S, we have defined the homomorphism and congruence on power series semi-ring and have obtained some important conclusions.
