Karakostas %J Electronic Journal of Differential Equations %D 2004 %I Texas State University %X The existence of triple positive solutions for a boundary-value problem governed by the $Phi$-Laplacian is investigated, when $Phi$ 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]. %K Boundary value problems %K positive solutions %K $Phi$-Laplacian %K Leggett-Williams fixed point theorem. %U http://ejde.math.txstate.edu/Volumes/2004/69/abstr.html
