Daqing Jiang, Donal O’Regan, Ravi P. Agarwal · Journal of Applied Analysis · 2005
This paper presents new existence results for singular discrete boundary value problems for the one-dimension p -Laplacian. In particular our nonlinearity may be singular in its dependent variable and is allowed to change sign. Our results are new even for p = 2.
