Stability of a generalization of the Fréchet functional equation
We prove some stability and hyperstability results for a generalization of the well known Fréchet functional equation, stemming from one of the characterizations of the inner product spaces. As the main tool we use a fixed point theorem for the function

Analysis of success of achieving fishing mortality levels for the Northwest Mediterranean Multi-annual plan. [PDF]
The evaluation of multi-annual plans to manage demersal fisheries performed by STECF (2016) is revisited to calculate an additional indicator of fishing mortality that better captures the effect of using ranges.

Hyperstability of Some Functional Equations on Restricted Domain
The paper concerns functions which approximately satisfy, not necessarily on the whole linear space, a generalization of linear functional equation. A Hyers-Ulam stability result is proved and next applied to give conditions implying the hyperstability ...

Almost Multi-Cubic Mappings and a Fixed Point Application [PDF]
The aim of this paper is to introduce $n$-variables mappings which are cubic in each variable and to apply a fixed point theorem for the Hyers-Ulam stability of such mapping in non-Archimedean normed spaces.

Stability of the Fréchet Equation in Quasi-Banach Spaces
We investigate the Hyers–Ulam stability of the well-known Fréchet functional equation that comes from a characterization of inner product spaces. We also show its hyperstability on a restricted domain. We work in the framework of quasi-Banach spaces.
