This paper concerns solutions to the Hardy–Hénon equation -Δu=|x|σupin Rn with n≥ 1 and arbitrary p,σ∈R. This equation was proposed by Hénon in 1973 as a model to study rotating stellar systems in astrophysics. Although there have been many works devoting to the study of the above equation, at least one of the following three assumptions p> 1 , σ≥ - 2 , and n≥ 3 is often assumed. The aim of this paper is to investigate the equation in other cases of these parameters, leading to a complete picture of the existence/non-existence results for non-trivial, non-negative solutions in the full generality of the parameters. In addition to the existence/non-existence results, the uniqueness of solutions is also discussed. © 2022, The Author(s).
