On a singular eigenvalue problem and its applications in computing the Morse index of solutions to semilinear PDE's
AL Amadori, F Gladiali - Nonlinear Analysis: Real World Applications, 2020 - Elsevier
We investigate nodal radial solutions to semilinear problems of type− Δ u= f (| x|, u) in Ω, u=
0 on∂ Ω, where Ω is a bounded radially symmetric domain of RN (N≥ 2) and f is a real …

[HTML][HTML] The Hénon problem with large exponent in the disc
AL Amadori, F Gladiali - Journal of Differential Equations, 2020 - Elsevier
In this paper we consider the Hénon problem in the unit disc with Dirichlet boundary
conditions. We study the asymptotic profile of least energy and nodal least energy radial …

Morse index computation for radial solutions of the Hénon problem in the disk
We compute the Morse index m (up) of any radial solution up of the semilinear problem:(P)−
