Periodic Solutions of Periodic Systems

1994
In this chapter we study the existence, stability and isolation of periodic solutions belonging to n-dimensional systems of periodic nonlinear differential equations of the form ẋ = f (t, x) where f is periodic in t with some period T > 0: f (t + T, x) = f (t,x).

On the existence of periodic solutions and almost periodic solutions for nonlinear systems

Nonlinear Analysis: Theory, Methods & Applications, 1995
The author presents dissipative type conditions which guarantee the existence and uniqueness of bounded, periodic and almost periodic solutions of a system \(x'= A(t, x)+ f(t)\), where the right-hand side is corresponding periodic or almost periodic.

The Existence of Periodic Solutions of Perturbed Periodic Systems

SIAM Journal on Applied Mathematics, 1971
Conditions are obtained for the existence of a periodic solution to $\dot x = f( {t,x} ) + g( {t,x} )$, where f and g are periodic in t. The technique used is the application of a fixed-point theorem to the iterates of the period map.

Breather Solutions in Periodic Media

Communications in Mathematical Physics, 2011
The authors consider nonlinear wave equations of the form \[ s(x) u_{tt} = u_{xx} - q(x) u + u^3, \] where \(s(x)\) and \(q(x)\) are \(a\)-periodic real-valued coefficients. They choose these coefficients in such a way that the linear problem, \[ q(x) w(x) - w''(x) - \omega^2 s(x) w(x) = 0, \] has finite spectral gaps near odd multiples of \(\omega_* =

Almost Periodic Solutions for Limit Periodic Systems

SIAM Journal on Applied Mathematics, 1972
A system of ordinary differential equations with limit periodic t-dependence has associated with it a sequence of approximating systems with periodic t-dependence. If each of these approximating systems has a periodic solution, sufficient conditions are given on these solutions under which the original system has an almost periodic solution. Additional

Periodic solutions of pendulum: II

Journal of Physics A: Mathematical and General, 2003
Summary: Period-3 oscillations of pendulum are investigated using the method developed in our previous paper [ibid. 33, No. 47, 8489--8505 (2000; Zbl 0972.70020)]. Values of the driving force within very narrow ranges may give rise to this kind of motion.
