Multiple positive solutions for singular boundary-value problems with derivative dependence on finite and infinite intervals. <i>Electronic Journal of Differential Equations, 2006</i>(74), pp. 1-25.1072-6691https://hdl.handle.net/10877/13947In this paper, Krasnoselskii's theorem and the fixed point theorem of cone expansion and compression are improved. Using the results obtained, we establish the existence of multiple positive solutions for the singular second-order boundary-value problems with derivative dependance on finite and infinite intervals.Text25 pages1 file (.pdf)enAttribution 4.0 InternationalKrasnoselskii's theoremSingular boundary value problemsFixed point theorem of cone expansion and compressionArticle
