Abstract

Let σ: \(E\longrightarrow E\) be an involution of the normed space E and let p, M, d be nonnegative real numbers, such that \(0<p<1\). In this chapter, we investigate the Hyers–Ulam–Rassias stability of the Pexider functional equations
$$\begin{aligned} f(x+y) = &\, g(x)+h(y),\ f(x+y)+g(x-y)=h(x)+k(y),\\ & f(x+y)+g(x+\sigma(y))=h(x)+k(y), x,y\in{E}\end{aligned}$$
on restricted domains \(\mathcal{B}=\{(x,y)\in{E^{2}}: \|x\|^{p}+\|y\|^{p}\geq M^{p}\}\) and \(\mathcal{C}=\{(x,y)\in{E}^{2}:\|x\|\geq d\; or\; \|y\|\geq d\}.\)
