Solvability of a third-order two-point boundary value problem
A new comparison theorem is proved and then used to investigate the solvability of a third-order two-point boundary value problem u′′′(t) + f(t, u(t), u′(t), u′′(t))) = 0, u(0) = u′(2π) = 0, u′′(0) = u′′(2π). Some existence results are established for this problem via upper and lower solutions method and fixed point theory. 2000MR Subject Classification: 34B15, 34C05
متن کاملSolvability for a System of Nonlinear Fractional Higher–order Three–point Boundary Value Problem
Existence of eigenvalues yielding single and multiple positive solutions for a system of higher order fractional differential equations along with boundary conditions is established. The results are obtained by the use of a Guo-Krasnosel’skii fixed point theorem in cones.
متن کاملSolvability of a Third-order Three-point Boundary Value Problem on a Half-line*
In this paper, we consider the solvability of a third-order three-point boundary value problem on a half-line of the form: { x′′′(t) = f(t, x(t), x′(t), x′′(t)), 0 < t < +∞, x(0) = αx(η), lim t→+∞ x(t) = 0, i = 1, 2, where α 6= 1 and η ∈ (0,+∞), while f : [0,+∞)× R → R is S − Carathéodory function. The existence and uniqueness of solutions for the boundary value problems are obtained by the Ler...
متن کاملGeneralized quasilinearization method for a second order three point boundary-value problem with nonlinear boundary conditions
The generalized quasilinearization technique is applied to obtain a monotone sequence of iterates converging uniformly and quadratically to a solution of three point boundary value problem for second order differential equations with nonlinear boundary conditions. Also, we improve the convergence of the sequence of iterates by establishing a convergence of order k.

and Applied Analysis 3 for 0 ≤ i ≤ n − 1, where α > 0 and β > 1 are given constants. On the one hand, the author established criteria for the existence of at least one solution and of at least one positive solution for the BVP 1.6 by using the Schauder fixed point theorem and Krasnosel’skii fixed point theorem, respectively. On the other hand, the author investigated the existence of multiple p...
