Radial solutions of truncated Laplacian equations in punctured balls
Isabeau Birindelli, Françoise Demengel, Fabiana Leoni
We consider equations involving the truncated laplacians and having lower order terms with singular potentials posed in punctured balls. We study both the principal eigenvalue prob…
Principal eigenvalues for Fully non linear singular or degenerate operators in punctured balls
Françoise Demengel
This paper is devoted to the proof of the existence of the principal eigenvalue and related eigenfunctions for fully nonlinear degenerate or singular uniformly elliptic equations p…
Mixed boundary value problems for fully nonlinear degenerate or singular equations
Isabeau Birindelli, Francoise Demengel, Fabiana Leoni
We prove existence, uniqueness and regularity results for mixed boundary value problems associated with fully nonlinear, possibly singular or degenerate elliptic equations. Our mai…
A Liouville theorem for fully nonlinear problems with infinite boundary conditions and applications
Isabeau Birindelli, Francoise Demengel, Fabiana Leoni
We prove a Liouville type classification theorem in half-spaces for infinite boundary value problems related to fully nonlinear, uniformly elliptic operators. We then apply the res…
regularity for singular or degenerate fully nonlinear operators and applications
Isabeau Birindelli, Francoise Demengel, Fabiana Leoni
In this note, we prove regularity for solutions of some fully nonlinear degenerate elliptic equations with "superlinear" and "subquadratic " Hamiltonian terms.…
Dirichlet problems for fully nonlinear equations with \lq subquadratic \lq Hamiltonians
Isabeau Birindelli, Francoise Demengel, Fabiana Leoni
For a class of fully nonlinear equations having second order operators which may be singular or degenerate when the gradient of the solutions vanishes, and having first order terms…
