A subsolution-supersolution method for quasilinear systems [PDF]

open access: yes
Summarization: Assuming that a system of quasilinear equations of gradient type admits a strict supersolution and a strict subsolution, we show that it also admits a positive ...

A Dirichlet problem in the strip

open access: yesElectronic Journal of Differential Equations, 1996
In this paper we investigate a Dirichlet problem in a strip and, using the sliding method, we prove monotonicity for positive and bounded solutions. We obtain uniqueness of the solution and show that this solution is a function of only one variable. From
