Sign-changing concentration phenomena of an anisotropic sinh-Poisson type equation with a Hardy or Hénon term

Qiang Ren

We consider the following anisotropic sinh-Poisson tpye equation with a Hardy or Hénon term: $$-\mathrm{div} (a(x)\nabla u)+ a(x)u=\varepsilon^2a(x)|x-q|^{2α}(e^u-e^{-u}) \quad\m…
