Homoclinic solutions for a differential inclusion system involving the p(t)-Laplacian

open access: yesAdvances 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 ...

Periodic solutions of quasi‐differential equations

open access: yesInternational Journal of Stochastic Analysis, Volume 9, Issue 1, Page 11-20, 1996., 1995
Existence principles and theorems are established for the nonlinear problem Lu = f(t, u) where Lu=−(pu′) ′+hu is a quasi‐differential operator and f is a Carathéodory function. We prove a maximum principle for the operator L and then we show the validity of the upper and lower solution method as well as the monotone iterative technique.

Nonresonance conditions for fourth order nonlinear boundary value problems

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 17, Issue 4, Page 725-740, 1994., 1994
This paper is devoted to the study of the problem We assume that f can be written under the form where r is a bounded function. We obtain existence conditions related to uniqueness conditions for the solution of the linear problem

Anti‐periodic traveling wave solutions to a class of higher‐order Kadomtsev‐Petviashvili‐Burgers equations

open access: yesInternational Journal of Stochastic Analysis, Volume 7, Issue 1, Page 1-12, 1994., 1993
We discuss the existence, uniqueness, and continuous dependence on data, of anti‐periodic traveling wave solutions to higher order two‐dimensional equations of Korteweg‐deVries type.

The method of lower and upper solutions for n th‐order periodic boundary value problems

open access: yesInternational Journal of Stochastic Analysis, Volume 7, Issue 1, Page 33-47, 1994., 1994
In this paper we develop the monotone method in the presence of lower and upper solutions for the problem where f is a Carathéodory function. We obtain sufficient conditions for f to guarantee the existence and approximation of solutions between a lower solution α and an upper solution β for n ≥ 3 with either α ≤ β or α ≥ β.

A class of singularly perturbed evolution systems

open access: yesInternational Journal of Stochastic Analysis, Volume 7, Issue 2, Page 179-190, 1994., 1994
In this paper we study a class of evolution equations where the semigroup generators are singularly perturbed by a nonnegative real valued function of time. Sufficient conditions for existence of evolution operators and their compactness are given including continuous dependence on the perturbation. Further, for a coupled system of singularly perturbed
