On the existence of periodic solution of perturbed generalized Li\'enard equations
Under conditions of Levinson-Smith type, we prove the existence of a $\tau$-periodic solution for the perturbed generalized Li\'enard equation u''+\phi(u,u')u'+\psi(u)=\epsilon\omega(\frac{t}{\tau},u,u') with periodic forcing term.

Almost periodic solution of a discrete competitive system with delays and feedback controls
A discrete nonlinear almost periodic multispecies competitive system with delays and feedback controls is proposed and investigated. We obtain sufficient conditions to ensure the permanence of the system.

(ω, c)- Pseudo almost periodic distributions
The paper is a study of the (w, c) −pseudo almost periodicity in the setting of Sobolev-Schwartz distributions. We introduce the space of (w, c) −pseudo almost periodic distributions and give their principal properties.

Ambrosetti–Prodi Periodic Problem Under Local Coercivity Conditions
In this paper we focus on the periodic boundary value problem associated with the Liénard differential equation x′′+f(x)x′+g(t,x)=s{x^{\prime\prime}+f(x)x^{\prime}+g(t,x)=s}, where s is a real parameter, f and g are continuous functions and g is T ...

Hopf bifurcation in a dynamic IS-LM model with time delay [PDF]
The paper investigates the impact of delayed tax revenues on the fiscal policy out-comes. Choosing the delay as a bifurcation parameter we study the direction and the stability of the bifurcating periodic solutions. We show when the system is stable with

Let n≥2{n\geq 2} be an integer, P=diag(-In-κ,Iκ,-In-κ,Iκ){P=\mathrm{diag}(-I_{n-\kappa},I_{\kappa},-I_{n-\kappa},I_{\kappa})} for some integer κ∈[0,n]{\kappa\in[0,n]}, and let Σ⊂ℝ2n{\Sigma\subset{\mathbb{R}}^{2n}} be a partially symmetric compact ...

Periodic Impact Motions at Resonance of a Particle Bouncing on Spheres and Cylinders
We investigate the existence of periodic trajectories of a particle, subject to a central force, which can hit a sphere or a cylinder. We will also provide a Landesman–Lazer-type condition in the case of a nonlinearity satisfying a double resonance ...
