On resonant discrete boundary value problems. (English) Zbl 0548.39003
This paper is concerned with resonant boundary value problems for systems of difference equations. The alternative method is used to establish computationally feasible sufficient conditions for the existence of solutions of weakly nonlinear systems. The results presented extend previous results of Halanay who considered the case of periodic boundary conditions.
