Asymptotic integration of linear differential equations

[摘要] We establish a new result on the asymptotic integration of linear differential systems of the form y' = (Lambda + R)y, where Lambda is diagonal and R is small. More specifically, we allow for different scales of asymptotic behaviour of the individual matrix elements of Lambda and R. We also discuss an application to a self-adjoint fourth Order equation.
