Hyers-Ulam stability of linear differential equations of second order.
(English)
[J] Appl. Math. Lett. 23, No. 3, 306-309 (2010). ISSN 0893-9659

Summary: We prove the Hyers-Ulam stability of linear differential equations of second order. That is, if $y$ is an approximate solution of the differential equation $y{^{\prime}}{^{\prime}}+\alpha y{^{\prime}}+\beta y=0$, then there exists an exact solution of the differential equation near to $y$.
