The Dirichlet problem for a prescribed anisotropic mean curvature equation
Résumé
We discuss existence, uniqueness, regularity and boundary behaviour of solutions of the Dirichlet problem for the prescribed anisotropic mean curvature equation
−div(∇u/1+|∇u|2)=−au+b/1+|∇u|2,
where a,b>0 are given parameters and Ω is a bounded Lipschitz domain in RN. This equation appears in the modeling theory of capillarity phenomena for compressible fluids and in the description of the geometry of the human cornea.
