Localization of Nonsmooth Lower and Upper Functions for Periodic Boundary Value Problems
In this paper we present conditions ensuring the existence and localization of lower and upper functions of the periodic boundary value problem u + k u = f(t, u), u(0) = u(2 ), u(0) = u(2 ), k ∈ , k 6= 0. These functions are constructed as solutions of some related generalized linear problems and can be nonsmooth in general.
متن کاملMethod of Lower and Upper Functions in Impulsive Periodic Boundary Value Problems
We present here new existence results for the nonlinear second order impulsive periodic boundary value problem. They rely on the presence of a pair of associated lower/upper functions. In contrast to the results known up to now, we need not assume that they are well-ordered.
متن کاملPeriodic Boundary Value Problems and Periodic Solutions of Second Order FDE with Upper and Lower Solutions∗
We use the monotone iterative technique with upper and lower solutions in reversed order to obtain two monotone sequences that converge uniformly to extremal solutions of second order periodic boundary value problems and periodic solutions of functional differential equations(FDEs).
متن کاملUpper and Lower Solutions Method for Fourth-order Periodic Boundary Value Problems
The purpose of this paper is to prove the existence of a solution of the following periodic boundary value problem ( u(t) = f(t, u(t), u′′(t)), t ∈ [0, 2π] u(0) = u(2π), u′(0) = u′(2π), u′′(0) = u′′(2π), u′′′(0) = u′′′(2π) in the presence of an upper solution β and a lower solution α with β ≤ α, where f(t, u, v) satisfies one side Lipschitz condition.
متن کاملOn Second Order Periodic Boundary-value Problems with Upper and Lower Solutions in the Reversed Order
In this paper, we study the differential equation with the periodic boundary value u′′(t) = f(t, u(t), u′(t)), t ∈ [0, 2π] u(0) = u(2π), u′(0) = u′(2π). The existence of solutions to the periodic boundary problem above with appropriate conditions is proved by using an upper and lower solution method.
