On the inverse stability of functional equations

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.

Stability of a generalization of the Fréchet functional equation

Renata Malejki (2015)

Annales Universitatis Paedagogicae Cracoviensis. Studia Mathematica

Similarity:

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 some function spaces. We end the paper with some new inequalities characterizing the inner product spaces.
