主 题:Hyers-Ulam stability Cauchy-Jensen additive functional equation fixedpoint non-Archimedean normed spaces
摘 要:Using the fixed point and direct methods, we prove the Hyers-Ulam stability of the following Cauchy-Jensen additive functional equation 2f(p∑i=1xi+q∑j=1yj+2d∑k=1zk/2)=p∑i=1f(xi)+q∑j=1f(yj)+2d∑k=1f(zk),where p, q, d are integers greater than 1, in non-Archimedean normed spaces.
