摘要
在拟Banach代数中同态的稳定性基础上引入了拟同态的概念,研究了Banach代数中与条件‖f(x1+x2+…+xk)-f(x1)-f(x2)-…-f(xk)‖≤θ‖x1‖r‖x2‖r…‖xk‖r,‖f(x1+x2+…+xk)-f(x1)-f(x2)-…-f(xk)‖≤θ(‖x1‖r+‖x2‖r+…+‖xk‖r)(r,θ是正实数)相关的Hyers-Ulam-Rassias稳定性问题.
Base of the stability of homorphism in quasi-Banach algebra, the notion of quasi-homomorphism is introduced, and Hyers-Ulam-Rassias stability of quasi-homorphism is investigated in quasi-Banach algebras associated to the following conditions：
{｜｜f（x1＋x2＋…＋xk）-f（x1）-f（x2）-…-f（xk）｜｜≤θ｜｜x1｜｜^r｜｜x2｜｜^r…｜｜xk｜｜^r,
｜｜f（x1＋x2＋…＋xk）-f（x1）-f（x2）-…-f（xk）｜｜≤θ｜｜x1｜｜^r＋｜｜x2｜｜^r＋…＋｜｜xk｜｜^r,）
where r and s be positive real numbers.
