Positive solutions of four-point boundary-value problems for higher-order with p-Laplacian operator. <i>Electronic Journal of Differential Equations, 2007</i>(05), pp. 1-14.1072-6691https://hdl.handle.net/10877/14155In this paper, we study the existence of positive solutions for nonlinear four-point singular boundary-value problems for higher-order equation with the p-Laplacian operator. Using the fixed-point index theory, we find conditions for the existence of one solution, and of multiple solutions.Text14 pages1 file (.pdf)enAttribution 4.0 InternationalHigher-order p-Laplacian operatorFour-pointPositive solutionsSingular boundary-valueFixed-point index theoryArticle
