Morse Index and Symmetry for Elliptic Problems with Nonlinear Mixed Boundary Conditions
Lucio Damascelli, Filomena Pacella
Under a Morse index condition we prove symmetry results for solutions of a nonlinear mixed boundary condition elliptic problem. As an intermediate step we relate the Morse index of…
Existence results for fully nonlinear equations in radial domains
Giulio Galise, Fabiana Leoni, Filomena Pacella
We consider the fully nonlinear problem \begin{equation*} \begin{cases} -F(x,D^2u)=|u|^{p-1}u & \text{in }\\ u=0 & \text{on } \end{cases} \end{equation*} where is…
Asymptotic profile of positive solutions of Lane-Emden problems in dimension two
Francesca De Marchis, Isabella Ianni, Filomena Pacella
We consider families of solutions to the problem \begin{equation}\label{problemAbstract} \left\{\begin{array}{lr}-Δu= u^p & \mbox{ in }Ω\\ u>0 & \mbox{ in }Ω\\ u=0 & \mbox{ o…
Asymptotic analysis for radial sign-changing solutions of the Brezis-Nirenberg problem in low dimensions
Alessandro Iacopetti, Filomena Pacella
We consider the classical Brezis-Nirenberg problem in the unit ball of , and analyze the asymptotic behavior of nodal radial solutions in the low dimensions…
A nonexistence result for sign-changing solutions of the Brezis-Nirenberg problem in low dimensions
Alessandro Iacopetti, Filomena Pacella
We consider the Brezis-Nirenberg problem: \begin{equation*} \begin{cases} -Δu = λu + |u|^{2^* -2}u & \hbox{in}\ Ω\\ u=0 & \hbox{on}\ \partial Ω, \end{cases} \end{equation*} where $…
On the pure critical exponent problem for the -Laplacian
Carlo Mercuri, Filomena Pacella
In this paper we prove existence and multiplicity of positive and sign-changing solutions to the pure critical exponent problem for the -Laplacian operator with Dirichlet bounda…
