Solutions of 2nth-Order Boundary Value Problem for Difference Equation via Variational Method
نویسندگان
چکیده
The variational method and critical point theory are employed to investigate the existence of solutions for 2nth-order difference equation Δ pk−nΔyk−n −1 n f k, yk 0 for k ∈ 1,N with boundary value condition y1−n y2−n · · · y0 0, yN 1 · · · yN n 0 by constructing a functional, which transforms the existence of solutions of the boundary value problem BVP to the existence of critical points for the functional. Some criteria for the existence of at least one solution and two solutions are established which is the generalization for BVP of the even-order difference equations.

Nonexistence and existence results for a 2$n$th-order $p$-Laplacian discrete Neumann boundary value problem
This paper is concerned with a 2nth-order p-Laplacian difference equation. By using the critical point method, we establish various sets of sufficient conditions for the nonexistence and existence of solutions for Neumann boundary value problem and give some new results. Results obtained successfully generalize and complement the existing ones.

In this paper, we consider a non-self-adjoint, singular, nonlinear fourth order boundary value problem which arises in the theory of epitaxial growth. It is possible to reduce the fourth order equation to a singular boundary value problem of second order given by w''-1/r w'=w^2/(2r^2 )+1/2 λ r^2. The problem depends on the parameter λ and admits multiple solutions. Therefore, it is difficult to...

We will show how to use the mountain pass theorem to obtain nontrivial solutions of a certain two point BVP for the 2nth order, n ∈ N (formally) self-adjoint nonlinear difference equation n ∑ i=0 [ri(t) u(t − i)] = f (t, u(t)), t ∈ [a, b]Z. No periodicity assumptions will be placed on ri, i = 0, 1, . . . , n or f and it will be assumed that f grows superlinearly both at the origin and at infini...
