Hill's Differential Equation

Published online by Cambridge University Press:  03 November 2016

Extract

1. We deal with the equation

where ψ(ωt)is continuous, periodic in t with period 2π/ω a, k2 are real and positive, and

A stable (bounded) solution was given by Erdélyi in 1934 employing a complicated transformation and integral equations.

We shall obtain this solution by an elementary method, thereby reducing the analysis to one-third of its former length.
