On the existence of bounded solutions for a nonlinear elliptic system
This work deals with the system (-Δ) mu = a(x) v p, (-Δ) mv = b(x) u q with Dirichlet boundary condition in a domain Ω ⊂ ℝ n, where Ω is a ball if n ≥ 3 or a smooth perturbation of a ball when n = 2. We prove that, under appropriate conditions on the parameters (a, b, p, q, m, n), any nonnegative so...

| Sumario: | This work deals with the system (-Δ) mu = a(x) v p, (-Δ) mv = b(x) u q with Dirichlet boundary condition in a domain Ω ⊂ ℝ n, where Ω is a ball if n ≥ 3 or a smooth perturbation of a ball when n = 2. We prove that, under appropriate conditions on the parameters (a, b, p, q, m, n), any nonnegative solution (u, v) of the system is bounded by a constant independent of (u, v). Moreover, we prove that the conditions are sharp in the sense that, up to some border case, the relation on the parameters are also necessary. The case m = 1 was considered by Souplet (Nonlinear Partial Differ Equ Appl 20:464-479, 2004). Our paper generalize to m ≥ 1 the results of that paper. © 2011 Fondazione Annali di Matematica Pura ed Applicata and Springer-Verlag. |
