| Abstract | |
In this paper we prove existence of least energy nodal solutions for the Hamiltonian elliptic system with Henon-type weights -Delta u = vertical bar x vertical bar(beta)vertical bar v vertical bar(q-1)v, -Delta u = vertical bar x vertical bar(alpha)vertical bar u vertical bar(q-1)u in Omega, u = v = 0 on partial derivative Omega where Omega is a bounded smooth domain in R-N, N >= 1, alpha, beta >= 0 and the nonlinearities are superlinear and subcritical, namely 1 > 1/p+1 + 1/q+1 > N - 2/N. When Omega is either a ball or an annulus centred at the origin and N >= 2, we show that these solutions display the so-called foliated Schwarz symmetry. It is natural to conjecture that these solutions are not radially symmetric. We provide such a symmetry breaking in a range of parameters where the solutions of the system behave like the solutions of a single equation. Our results on the above system are new even in the case of the Lane-Emden system (i.e. without weights). As far as we know, this is the first paper that contains results about least energy nodal solutions for strongly coupled elliptic systems and their symmetry properties. (C) 2015 Elsevier Masson SAS.
