On the number of positive solutions of nonlinear systems. (English) Zbl 1036.34032
This paper is devoted to the existence, multiplicity and nonexistence of positive solutions to boundary value problems on $[0,1]$ for a class of second-order differential systems where the main common operator is the one-dimensional $p$-Laplacian, $p> 1$. The author uses a fixed-point theorem in a cone due to {\it M. A. Krasnoselskij} [Positive solutions of operator equations. Groningen: The Netherlands: P. Noordhoff Ltd. (1964; Zbl 0121.10604)].
