Multiple positive solutions to fourth-order singular boundary-value problems in abstract spaces
Electronic journal of differential equations, Tome 2004 (2004)
We prove the existence of multiple positive solutions to singular boundary-value problems for fourth-order equations in abstract spaces. Our results improve and extend that obtained in [14,15,16], even in the scalar case.
