Sign-changing solutions for critical Hamiltonian systems in ${\mathbb{R}}^N$

Yuxia Guo, Seunghyeok Kim, Angela Pistoia +1

We build infinitely many geometrically distinct non-radial sign-changing solutions for the Hamiltonian-type elliptic systems $$ -Δu =|v|^{p-1}v\ \hbox{in}\ \mathbb{R}^N,\ -Δv =|u…
