Stability property of functional equations in modular spaces: a fixed-point approach
This paper is devoted to the problem of stability of quadratic functional equations in modular metric spaces in the Hyers-Ulam-Rassias sense. More precisely, the functional equation here considered is the Pappus functional equation, which arises from some geometrical considerations. The obtained results generalize previously known findings about the considered equation.
