متن کاملPositive Periodic Solutions of Nonlinear First-order Functional Difference Equations with a Parameter
We obtain the existence and multiplicity of positive T -periodic solutions for the difference equations ∆x(n) = a(n, x(n))− λb(n)f(x(n− τ(n))) and ∆x(n) + a(n, x(n)) = λb(n)f(x(n− τ(n))), where f(·) may be singular at x = 0. Using a fixed point theorem in cones, we extend recent results in the literature.

متن کاملPositive Periodic Solutions of Singular First Order Functional Difference Equation
In this paper, we consider the following singular first order functional difference equation Δx(k) = −a(k)x(k) + λb(k)f(x(k − τ(k))), k ∈ Z where f(.) is singular at x = 0. By using a Kranoselskii fixed point theorem, we will establish the existence and multiplicity of positive periodic solutions for the above problem. The results obtained are new, and some examples are given to illustrate our ...
