Rassias, John Michael
On a new approximation of approximately linear mappings by linear mappings. (English)
[J] Discuss. Math. 7, 193-196 (1985). ISSN 0137-9747

Assume A is a normed linear space, B is a Banach space, and $f: A\to B$ is a mapping "approximately linear". In this paper we solve the following Ulam Problem: "Give conditions in order for a linear mapping near an approximately linear mapping to exist".
