چکیده
We obtain optimal boundary and global regularity estimates for viscosity solutions of fully nonlinear elliptic equations whose ellipticity degenerates at the critical points a given solution. show that any solution is C1,α on domain, an explicit α only in terms datum degeneracy degree, independent operator. also sharp estimates. use different method from all previous results nature, which give some small α>0. Our findings are new even model equations, involving degenerate Laplacian. On obtient des estimations de régularité optimales, globales et sur la frontière d'un domaine, viscosité du problème Dirichlet pour opérateurs complètement non-linéaires dont l'ellipticité dégénère en un point critique montre que toute est explicite, donné seulement par donnée au bord le degré dégénérescence l'opérateur, indépendant l'opérateur elliptique. aussi exactes. utilise une méthode différente travaux précédents qui donnent petit. Nos résultats sont nouveaux même les équations modèles font intervenir Laplacien dégénéré.

Boundary Regularity for Viscosity Solutions of Fully Nonlinear Elliptic Equations
We provide regularity results at the boundary for continuous viscosity solutions to nonconvex fully nonlinear uniformly elliptic equations and inequalities in Euclidian domains. We show that (i) any solution of two sided inequalities with Pucci extremal operators is C1,α on the boundary; (ii) the solution of the Dirichlet problem for fully nonlinear uniformly elliptic equations is C2,α on the b...
متن کاملDegenerate Conformally Invariant Fully Nonlinear Elliptic Equations
There has been much work on conformally invariant fully nonlinear elliptic equations and applications to geometry and topology. See for instance [17], [5], [4], [10], [14], [9], and the references therein. An important issue in the study of such equations is to classify entire solutions which arise from rescaling blowing up solutions. Liouville type theorems for general conformally invariant fu...
متن کاملInterior Regularity of Fully Nonlinear Degenerate Elliptic Equations I: Bellman Equations with Constant Coefficients
This is the first of a series of papers on the interior regularity of fully nonlinear degenerate elliptic equations of second order. We consider here a stochastic optimal control problem in a domain, in which the diffusion coefficients, drift coefficients and discount factor are independent of the spatial variables. Under appropriate assumptions, for k = 0, 1, when the terminal and running payo...

در این رساله به بررسی رفتار جواب های رده ای از معادلات دیفرانسیل با مشتقات جزیی در دامنه های کراندار می پردازیم . این معادلات به فرم نیم-خطی و غیر خطی برای مسایل مستقیم و معکوس مورد مطالعه قرار می گیرند . به ویژه، تاثیر شرایط مختلف فیزیکی را در مساله، نظیر وجود موانع و منابع، پراکندگی و چسبندگی در معادلات موج و گرما بررسی می کنیم و به دنبال شرایطی می گردیم که متضمن وجود سراسری یا عدم وجود سراسر...
Regularity Results for Very Degenerate Elliptic Equations
We consider a family of elliptic equations introduced in the context of traffic congestion. They have the form ∇·(∇F(∇u)) = f , where F is a convex function which vanishes inside some convex set and is elliptic outside. Under some natural assumptions on F and f , we prove that the function ∇F(∇u) is continuous in any dimension, extending a previous result valid only in dimension 2 [14]. Résumé....
