L’équation de translation et l’équation de Sincov généralisée
(1999)
On donne une liaison entre l’équation de translation (1) et l’équation de Sincov généralisée (2), aussi dans le cas du type de
Pexider ((20) et (23)). On formule aussi quelques problèmes ouverts.
Translation equation and the Jordan non-measurable continuous functions
(2017)
A connection between the continuous translation equation and the
Jordan non-measurable continuous functions is given.
On the stability of the squares of some functional equations
(2015)
We consider the stability, the superstability and the inverse stability
of the functional equations with squares of Cauchy’s, of Jensen’s and of
isometry equations and the stability in Ulam-Hyers sense of the alternation
of ...
Unstable (Stable) system of stable (unstable) functional equations
(2010)
In this note the answer to a question by Z. Moszner from the paper [1] about connections of stability of separate
equations and the system of them, is given.
On stability of some functional equations and topology of their target spaces
(2012)
Some remarks about the coherence of the stability of several functional equations with topology of their target
spaces are given. The equations in question are: homogeneity (first of all) and quadratic ones, as well as ...
