چکیده
|
In this paper, we solve the quadratic α-functional equations 2f(x) + 2f(y) = f(x + y) + α^-2f(α(x - y)), where α is a fixed non-archimedean number with α^-2 ≠ 3. using the fixed point method and the direct method, we prove the hyers-ulam stability of the functional equation (0.1) in non-archimedean banach spaces.
