A system of order 2 in which small sub-harmonics and large sub-harmonics coexist
Published online by Cambridge University Press: 14 November 2011
Synopsis
This paper establishes the coexistence of small and large subharmonics in a special case of the ordinary non-linear differential equation
of order 2, where κ, ε are small parameters, λ>0 is a parameter independent of κ, ε, h(t) has the least period 2π and
It is divided into three sections. In Section 1 a general analysis of the periodic solutions of (.), classified into small, medium or large, is given. In Section 2 the general theory of Section 1 is applied to the special form of (.) where k = vε1+s, v>0, s>0 constants, to obtain results from which we extract in Section 2 a theorem (Section 3) on the coexistence of a small periodic solution of order 1, several small sub-harmonics and several large sub-harmonics of the special case
of (.), where Q≧1 is an integer.
