,Selections of Set-valued Maps Satisfying Some Inclusions and the Hyers–Ulam Stability,We present a survey of several results on selections of some set-valued functions satisfying some inclusions and also on stability of those inclusions. Moreover, we show their consequences concerning stability of the corresponding functional equations.

,Generalized Ulam–Hyers Stability Results: A Fixed Point Approach,We show that a recent fixed point result in (C?dariu et al., Abstr. Appl. Anal., 2012) can be used to prove some generalized Ulam–Hyers stability theorems for additive Cauchy functional equation as well as for the monomial functional equation in .-normed spaces.

A Functional Equation Having Monomials and Its Stability,We use some results about the Fréchet functional equation to consider the following functional equation:. We also apply a fixed point method and homogeneous functions of degree α to investigate some stability results for this functional equation in β-Banach spaces.
