Existence and multiplicity of positive solutions for a Dirichlet boundary value problem in R-2
We deal with the Dirichlet boundary value problem associated to a parameter-dependent second order vector differential equation. Using the method of lower and upper solutions together with degree theory, we provide existence and multiplicity of positive solutions.
