DOI: 10.1080/00036811.2017.1343464

Abstract: Abstract We consider two types of infinite systems of second-order differential equations with boundary conditions in the Banach sequence space c. For each system, sufficient conditions are provided for the existence of solutions. Our approach… read more here.

DOI: 10.3390/sym14010108

Abstract: We perform Lie analysis for a system of higher order difference equations with variable coefficients and derive non-trivial symmetries. We use these symmetries to find exact formulas for the solutions in terms of k. Furthermore,… read more here.
