The existence of three positive solutions of a singular pp-Laplacian problem

We establish the existence of three positive solutions of the pp-Laplacian problem, which involves a singular nonlinearity. Three solutions are obtained by using the cutoff argument and the three critical points theorem proved by Ricceri (2000) in [15] and Bonanno (2003) in [12], provided the nonlinear term is a (p−1)(p−1)-sublinear growth at infinity.
