Fixed point methods for the generalized stability of functional equations in a single variable. (English)
[J] Fixed Point Theory Appl. 2008, Article ID 749392, 15 p. (2008). ISSN 1687-1812/e

Summary: We discuss the generalized Ulam-Hyers stability for functional equations in a single variable, including the nonlinear functional equations, the linear functional equations, and a generalization of functional equation for the square root spiral. The stability results have been obtained by a fixed point method. This method introduces a metrical context and shows that the stability is related to some fixed point of a suitable operator.
