Abstract
In this note we formulate sufficient conditions under which a certain class of nonlinear and nonautonomous differential equations of second order is Hyers–Ulam stable. This class consists of equations obtained by perturbing Hill’s equation of the form \(x''=(\lambda ^2(t)-\lambda '(t))x\).
We’re sorry, something doesn't seem to be working properly.
