A new critical curve for a class of quasilinear elliptic systems
We study a class of systems of quasilinear differential inequalities
associated to weakly coercive differential operators and power reaction terms.
The main model cases are given by the -Laplacian operator as well as the
mean curvature operator in non parametric form. We prove that if the exponents
lie under a certain curve, then the system has only the trivial solution. These
results hold without any restriction provided the possible solutions are more
regular. The underlying framework is the classical Euclidean case as well as
the Carnot groups setting.Comment: 28 page
Entire solutions of quasilinear elliptic systems on Carnot Groups
We prove general a priori estimates of solutions of a class of quasilinear
elliptic system on Carnot groups. As a consequence, we obtain several non
existence theorems. The results are new even in the Euclidean setting.Comment: 21 pages submitte
