Stability of Volterra difference delay equations.
Boundedness and stability in nonlinear delay difference equations employing fixed point theory.
Existence and positivity of solutions for a nonlinear periodic differential equation
We study the existence and positivity of solutions of a highly nonlinear periodic differential equation. In the process we convert the differential equation into an equivalent integral equation after which appropriate mappings are constructed. We then employ a modification of Krasnoselskii’s fixed point theorem introduced by T. A. Burton ([4], Theorem 3) to show the existence and positivity of solutions of the equation.
