Existence of periodic solutions with prescribed minimal period of a 2nth-order discrete system
In this paper, we concern with a 2nth-order discrete system. Using the critical point theory, we establish various sets of sufficient conditions for the existence of periodic solutions with prescribed minimal period. To the best of our knowledge, this is

This paper provides a uniqueness result for positive solutions of the Neumann and periodic boundary value problems associated with the ϕ-Laplacian equation (ϕ(u′))′+a(t)g(u)=0,(\phi \left(u^{\prime} ))^{\prime} +a\left(t)g\left(u)=0, where ϕ is a ...

Topological structure of solution sets of differential inclusions: the constrained case
We survey and announce some current results on the existence, the viability, and the topological structure of the viable solutions of differential equations and inclusion in Banach spaces under set constraints. Some new results concerning semilinear differential inclusions with state variables constrained to the so‐called regular and strictly regular ...

Center conditions for a simple class of quintic systems
We obtained center conditions for an O‐symmetric system of degree 5 for which the origin is a uniformly isochronous singular point.

Oscillation of a Circular Cylinder Subject to Water Jet [PDF]
Oscillation of a circular cylinder subject to water jet is analyzed theoretically, taking into outgoing film flow followed by hydraulic jump, which is considered to be almost similar to oblique impingement of a circular jet to a flat surface.

In this paper, we consider an almost periodic commensal symbiosis model with nonlinear harvesting on time scales. We establish a criterion for the existence and uniformly asymptotic stability of unique positive almost periodic solution of the system. Our

Homoclinic solutions for a differential inclusion system involving the p(t)-Laplacian
The aim of this article is to study nonlinear problem driven by the p(t)p\left(t)-Laplacian with nonsmooth potential. We establish the existence of homoclinic solutions by using variational principle for locally Lipschitz functions and the properties of ...
