On the stability of the nonlinear Euler-Lagrange functional equation in real normed linear spaces

1993
Let \(X\) be a real linear normed space and \(Y\) be a real Banach space. Assume that there exist \(c_ 2 \geq 0\), \(a,b\) for which \(r = a + b \in \mathbb{R} \backslash \{2\}\) such that \[ \biggl \| f(x+y) + f(x-y) - 2 \bigl[ f(x) + f(y) \bigr] \biggr \| \leq c_ 2 \| x \|^ a \| y \|^ b \] for \(x,y\in X\).
