On the Hyers-ulam Stability of Quadratic Functional Equations
In this paper, we obtain the general solution and the generalized Hyers-Ulam stability for quadratic functional equations f(2x+ y)+ f(2x− y) = f(x+ y)+ f(x− y)+6f(x) and f(2x + y) + f(x + 2y) = 4f(x + y) + f(x) + f(y).
متن کاملGeneralized Hyers–ulam Stability of Refined Quadratic Functional Equations
In this paper, we give a general solution of a refined quadratic functional equation and then investigate its generalized Hyers–Ulam stability in quasi-normed spaces and in non-Archimedean normed spaces. AMS Subject Classification: 39B82, 39B62
متن کاملHyers-ulam stability of functional equations with a square-symmetric operation.
The stability of the functional equation f(x composite function y) = H(f(x), f(y)) (x, y in S) is investigated, where H is a homogeneous function and composite function is a square-symmetric operation on the set S. The results presented include and generalize the classical theorem of Hyers obtained in 1941 on the stability of the Cauchy functional equation.
متن کاملOn a Generalized Hyers-Ulam Stability of Trigonometric Functional Equations
The Hyers-Ulam stability problems of functional equations go back to 1940 when S. M. Ulam proposed a question concerning the approximate homomorphisms from a group to a metric group see 1 . A partial answer was given by Hyers et al. 2, 3 under the assumption that the target space of the involved mappings is a Banach space. After the result of Hyers, Aoki 4 , and Bourgin 5, 6 dealt with this pro...
