Abstract:

Under some suitable local conditions and superlinear or sublinear conditions, we establish the multiplicity of positive solutions for a class of singular semipositone multi-point boundary value problem. Our results extend and improve some existing results of previous literatures for two-point and multi-point boundary value problems in the positone and in the semipositone cases.

Key words: Singular boundary value problems, Semipositone,  Positive solutions, Fixed point, Cone
