Abstract
In the study of problems of the type , conditions are generally imposed on the asymptotic behaviour of
with respect to the spectrum of
. To study the quasi-linear problems
type, we introduce a notion of spectrum for
that takes into account the dependence of the right-hand side with respect to the
gradient. The object of this work is to define, study and apply this new notion of spectrum.
