A unique continuation property for linear elliptic systems and nonresonance problems. (English) Zbl 0989.35048
From authors’ abstract: The aim of this paper is to study the existence of solutions for a quasilinear elliptic system where the nonlinear term is a Caratheodory function on a bounded domain of $$\mathbb R^N$$, by using the well known unique continuation property for elliptic system in all dimensions and the strict monotony of eigensurfaces. These properties allow us to consider the above problem as a nonresonance problem.
