A min‐max theorem and its applications to nonconservative systems
International Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 17, Page 1101-1110, 2003., 2003 A nonvariational generation of a min‐max principle by A. Lazer is made. And it is used to prove a new existence results for a nonconservative systems of ordinary differential equations with resonance.

Topological structure of solution sets of differential inclusions: the constrained case
Abstract and Applied Analysis, Volume 2003, Issue 6, Page 325-351, 2003., 2003 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 ...

A class of differential systems of even degree with exact non-algebraic limit cycles
, 2020 Up until now all the polynomial differential systems for which non- algebraic limit cycles are known explicitly have degree odd. Here we show that that there are polynomial systems of even degree with explicit no-algebraic limit cycles. To our knowledge,

Center conditions for a simple class of quintic systems
International Journal of Mathematics and Mathematical Sciences, Volume 29, Issue 11, Page 625-632, 2002., 2002 We obtained center conditions for an O‐symmetric system of degree 5 for which the origin is a uniformly isochronous singular point.

Open Mathematics, 2019 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
Advances in Nonlinear Analysis, 2022 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 ...

Existence of periodic solution for first order nonlinear neutral delay equations
International Journal of Stochastic Analysis, Volume 14, Issue 2, Page 189-194, 2001., 2001 In this paper by using the coincidence degree theory, sufficient conditions are given for the existence of periodic solutions of the first order nonlinear neutral delay differential equation.

Oscillation of a Circular Cylinder Subject to Water Jet [PDF]
, 2019 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.

Periodic solutions of a class of non‐autonomous second‐order differential inclusions systems
Abstract and Applied Analysis, Volume 6, Issue 3, Page 151-161, 2001., 2001 Using an abstract framework due to Clarke (1999), we prove the existence of periodic solutions for second‐order differential inclusions systems.
