A class of elliptic equations in anisotropic spaces

The equation Δu + V(x)u + b(x)u|u| ^{ρ -1} + h(x) = 0 in ${\mathbb{R}^{n}}$ is studied in anisotropic Lebesgue spaces. We assume ${\frac{n-\theta}{n-2} < \rho < \infty}$ , with n ≥ 3 and 0 ≤ θ < 2, which covers the supercritical range. Our approach relies on estimates of the Riesz potential and allows us to consider a wide class of potentials V, including anisotropic ones. The symmetry and antisymmetry of the solutions are also addressed.
