Multiple Positive Solutions of Second-Order Nonlinear Difference Systems with Repulsive Singularities
We study the existence of positive solutions for second-order nonlinear repulsive singular difference systems with periodic boundary conditions. Our nonlinearity may be singular in its dependent variable. The proof of the main result relies on a fixed point theorem in cones and a nonlinear alternati...
