Positive Periodic Solutions in Neutral Delay Difference Equations
We use Krasnoselskii’s fixed point theorem to obtain sufficient conditions for the existence of a positive periodic solution of the neutral delay difference equation x(n+ 1) = a(n)x(n) + c∆x(n− τ) + g(n, x(n− τ)). AMS Subject Classifications: 39A10, 39A12.
متن کاملA Finite Difference Method for Symmetric Positive Differential Equations
A finite difference method is developed for solving symmetric positive differential equations in the sense of Friedrichs. The method is applicable to partial differential equations of mixed type with more general boundary conditions. The method is shown to have a convergence rate of 0(hxl2), h being the size of mesh grid. Some numerical results are presented for a model problem of forward-backw...
متن کاملPOSITIVE PERIODIC SOLUTIONS FOR HIGHER-ORDER FUNCTIONAL q-DIFFERENCE EQUATIONS
In this paper, using the recently introduced concept of periodic functions in quantum calculus, we study the existence of positive periodic solutions of a certain higher-order functional q-difference equation. Just as for the well-known continuous and discrete versions, we use a fixed point theorem in a cone in order to establish the existence of a positive periodic solution. This paper is dedi...
متن کاملPositive Periodic Solutions for Neutral Functional Difference Equations
In this paper, we apply fixed point theorem in a cone to obtain sufficient conditions for the existence of single and multiple positive periodic solutions for a class of neutral functional difference equation. AMS Subject Classifications: 39A10, 39A11.
متن کاملExistence of Positive Solutions for Certain Partial Difference Equations
where Pm,n > 0 onN 0 , k, l ∈N0,Ni = {i, i+1, . . .} and i is an arbitrary integer. Throughout this paper, we assume that a, b, c, d are positive constants. A double sequence {Am,n} is said to be a solution of (1.1) if it satisfies (1.1) form≥m0, n≥ n0. A solution {Ai, j} of (1.1) is said to be eventually positive if Ai, j > 0 for all large i and j, and eventually negative if Ai, j < 0 for all ...
