An eigenvalue interval of solutions for a singular discrete boundary value problem with sign changing nonlinearities

Abstract

In this paper, we establish the existence of an eigenvalue interval of solutions to the singular discrete boundary value problem

where our nonlinearity may be singular in its dependent variable and is allowed to change sign.

Keywords:

• Singular discrete boundary value problems
• Positive solution
• Upper and lower solution
