Eule r-Lag range 型三次泛函方程的稳定性问题
Stability of the Euler-Lagrange type cubic functional equation
摘要
Abstract
Firstly ,the new Euler‐Lagrange type cubic functional equation f (x+ y -2z)+f(y+ z -2x)+ f(z+ x -2y)+ 6f (x+ y+ z)= 9[f (x+ y)+ f (y+ z)+ f (z + x)] -18[f(x)+ f(y)+ f(z)] in Banach spaces was investigated .Secondly ,equivalence of six functional equations was discussed . Lastly , by using the fixed pointed alternative , the general solution to the above functional equation was given and the stability of cubic functional equation was proved .关键词
