We prove, using the fixed point approach, some stability results for the general linear
functional equation. Namely we obtain sufficient conditions for the stability of a wide class of …

Given a bounded function Φ: R→ R, we define the Takagi type function TΦ: R→ R by The
main results of the paper provide sufficient conditions on Φ in order that TΦ be …

In this article, we employ a version of some fixed point theory (FPT) to obtain stability results
for the symmetric functional equation (FE) of q-Wright affine functions in non-Archimedean …

Abstract The Hyers–Ulam stability of a generalization of the functional equation of p-Wright
affine functions in normed spaces is studied. We give sufficient conditions for stability of this …
