On the Hyers-Ulam stability of the Banach space-valued differential equation \(y'=\lambda y\). (English) Zbl 1011.34046

The Hyers-Ulam stability is analyzed for the differential equation \(y'=\lambda y\), where \(y\) maps an open interval of \(\mathbb{R}\) into a complex Banach space. The authors prove a sufficient condition that allows one to estimate the distance between some given function \(\varphi\) and the set of all solutions to the differential equation above.
