Periodic Boundary Value Problems on Time Scales
We extend the results concerning periodic boundary value problems from the continuous calculus to time scales. First we use the Schauder fixed point theorem and the concept of lower and upper solutions to prove the existence of the solutions and then we investigate a monotone iterative method which could generate some of them. Since this method does not work on each time scale, a condition cont...
متن کاملMonotone Iterative Technique for First-Order Nonlinear Periodic Boundary Value Problems on Time Scales
Recently, periodic boundary value problems PBVPs for short for dynamic equations on time scales have been studied by several authors by using the method of lower and upper solutions, fixed point theorems, and the theory of fixed point index. We refer the reader to 1–10 for some recent results. In this paper we are interested in the existence of positive solutions for the following first-order P...

متن کاملPeriodic Boundary Value Problems for Second-Order Functional Differential Equations
Upper and lower solution method plays an important role in studying boundary value problems for nonlinear differential equations; see 1 and the references therein. Recently, many authors are devoted to extend its applications to boundary value problems of functional differential equations 2–5 . Suppose α is one upper solution or lower solution of periodic boundary value problems for second-orde...
متن کاملNonmonotone Impulse Effects in Second-order Periodic Boundary Value Problems
We deal with the nonlinear impulsive periodic boundary value problem u′′ = f (t,u,u′), u(ti+) = Ji(u(ti)), u′(ti+) = Mi(u′(ti)), i= 1,2, . . . ,m, u(0) = u(T), u′(0) = u′(T). We establish the existence results which rely on the presence of a well-ordered pair (σ1,σ2) of lower/upper functions (σ1 ≤ σ2 on [0,T]) associated with the problem. In contrast to previous papers investigating such proble...
