Estimates for eigenvalues of quasilinear elliptic systems

Mostrar todas las versiones(3)

In this paper we introduce the generalized eigenvalues of a quasilinear elliptic system of resonant type. We prove the existence of infinitely many continuous eigencurves, which are obtained by variational methods. For the one-dimensional problem, we obtain an hyperbolic type function defining a reg...
