Periodic Solutions for Nonlinear Evolution Equations with Non-instantaneous Impulses

Michal FečkanJinRong WangYong Zhou — 2014

Nonautonomous Dynamical Systems

In this paper, we consider periodic solutions for a class of nonlinear evolution equations with non-instantaneous impulses on Banach spaces. By constructing a Poincaré operator, which is a composition of the maps and using the techniques of a priori estimate, we avoid assuming that periodic solution is bounded like in [1-4] and try to present new sufficient conditions on the existence of periodic mild solutions for such problems by utilizing semigroup theory and Leray-Schauder's fixed point theorem....

On the nonlocal Cauchy problem for semilinear fractional order evolution equations

JinRong WangYong ZhouMichal Fečkan — 2014

Open Mathematics

In this paper, we develop the approach and techniques of [Boucherif A., Precup R., Semilinear evolution equations with nonlocal initial conditions, Dynam. Systems Appl., 2007, 16(3), 507–516], [Zhou Y., Jiao F., Nonlocal Cauchy problem for fractional evolution equations, Nonlinar Anal. Real World Appl., 2010, 11(5), 4465–4475] to deal with nonlocal Cauchy problem for semilinear fractional order evolution equations. We present two new sufficient conditions on existence of mild solutions. The first...

Novel method for generalized stability analysis of nonlinear impulsive evolution equations

JinRong WangYong ZhouWei Wei — 2012

Kybernetika

In this paper, we discuss some generalized stability of solutions to a class of nonlinear impulsive evolution equations in the certain piecewise essentially bounded functions space. Firstly, stabilization of solutions to nonlinear impulsive evolution equations are studied by means of fixed point methods at an appropriate decay rate. Secondly, stable manifolds for the associated singular perturbation problems with impulses are compared with each other. Finally, an example on initial boundary value...

Existence for nonoscillatory solutions of higher order nonlinear neutral differential equations

Yong ZhouBing Gen ZhangY. Q. Huang — 2005

Czechoslovak Mathematical Journal

Consider the forced higher-order nonlinear neutral functional differential equation d n d t n [ x ( t ) + C ( t ) x ( t - τ ) ] + i = 1 m Q i ( t ) f i ( x ( t - σ i ) ) = g ( t ) , t t 0 , where n , m 1 are integers, τ , σ i + = [ 0 , ) , C , Q i , g C ( [ t 0 , ) , ) , f i C ( , ) , ( i = 1 , 2 , , m ) . Some sufficient conditions for the existence of a nonoscillatory solution of above equation are obtained for general Q i ( t ) ( i = 1 , 2 , , m ) and g ( t ) which means that we allow oscillatory Q i ( t ) ( i = 1 , 2 , , m ) and g ( t ) . Our results improve essentially some known results in the references.

Fractional q -difference equations on the half line

Saïd AbbasMouffak BenchohraNadjet LaledjYong Zhou — 2020

Archivum Mathematicum

This article deals with some results about the existence of solutions and bounded solutions and the attractivity for a class of fractional q -difference equations. Some applications are made of Schauder fixed point theorem in Banach spaces and Darbo fixed point theorem in Fréchet spaces. We use some technics associated with the concept of measure of noncompactness and the diagonalization process. Some illustrative examples are given in the last section.

Mathematica Bohemica

In this paper we consider the nonlinear difference equation with several delays ( a x n + 1 + b x n ) k - ( c x n ) k + i = 1 m p i ( n ) x n - σ i k = 0 where a , b , c ( 0 , ) , k = q / r , q , r are positive odd integers, m , σ i are positive integers, { p i ( n ) } , i = 1 , 2 , , m , is a real sequence with p i ( n ) 0 for all large n , and lim inf n p i ( n ) = p i < , i = 1 , 2 , , m . Some sufficient conditions for the oscillation of all solutions of the above equation are obtained.
