Triple positive solutions for the Φ-Laplacian when Φ is a sup-multiplicative-like function. <i>Electronic Journal of Differential Equations, 2004</i>(69), pp. 1-13.1072-6691https://hdl.handle.net/10877/13422The existence of triple positive solutions for a boundary-value problem governed by the Φ-Laplacian is investigated, when Φ is a so-called sup-multiplicative-like function (in a sense introduced in [22]) and the boundary conditions include nonlinear expressions at the end points (as in [21, 28]). The Leggett-Williams fixed point theorem in a cone is used. The results improve and generalize known results given in [21].Text13 pages1 file (.pdf)enAttribution 4.0 InternationalBoundary value problemsPositive solutionsΦ-LaplacianLeggett-Williams fixed point theoremArticle
