A Focal Boundary Value Problem for Difference Equations
The eigenvalue problem in difference equations, (--1)n-kAny(t) A l:,=o p()’,(), with y(0) 0, 0 < < k, Ak+iy(T + 1) 0, 0 _< < n k, is examined. Under suitable conditions on the coefficients Pi, it is shown that the smallest positive eigenvalue is a decreasing function of T. As a consequence, results concerning the first focal point for the boundary value problem with A are obtained.
متن کاملThe Dirichlet and Focal Boundary Value Problems for Higher Order Quasi-halflinear Singular Differential Equations
For higher order quasi-halflinear singular differential equations, the Dirichlet and focal boundary value problems are considered. Analogues of the Fredholm first theorem are proved and on the basis of these results optimal in some sense sufficient conditions of solvability of the above-mentioned problems are found. îâäæñéâ. éŽôŽèæ îæàæï çãŽäæ êŽýâãîŽáûîòæãæ ïæêàñèŽîñèæ áæòâîâêùæŽèñîæ àŽêðëèâIJ...
متن کاملPositive Solutions of a Singular Positone and Semipositone Boundary Value Problems for Fourth-Order Difference Equations
This paper studies the boundary value problems for the fourth-order nonlinear singular difference equationsΔ4u i−2 λα i f i, u i , i ∈ 2, T 2 , u 0 u 1 0, u T 3 u T 4 0. We show the existence of positive solutions for positone and semipositone type. The nonlinear term may be singular. Two examples are also given to illustrate the main results. The arguments are based upon fixed point theorems i...
متن کاملSingular Higher Order Boundary Value Problems for Ordinary Differential Equations
This paper is somewhat of an extension of the recent work done by Kunkel [6]. Kunkel looked at an extension of Rachu̇nková and Rachu̇nek’s work where they studied a second order singular boundary value problem for the discrete p-Laplacian, φp(x) = |x|x [7]. Kunkel’s results extend theirs to the second order differential case, but only for p = 2, i.e. φ2(x) = x. In this paper, we extend Kunkel’s w...
