On the stability of the squares of some functional equations

Zenon Moszner (2015)

Annales Universitatis Paedagogicae Cracoviensis. Studia Mathematica

Similarity:

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 functional equations and of the equation of isometry.

On the inverse stability of functional equations

Zenon Moszner (2013)

Banach Center Publications

Similarity:

The inverse stability of functional equations is considered, i.e. when the function, approximating a solution of the equation, is an approximate solution of this equation.
