A Priori Estimates of Positive Solutions for Sublinear Elliptic Equations
نویسنده
چکیده
In this paper, a priori estimates of positive solutions for sublinear elliptic equations are given in terms of thicknesses of domains. To this end, a supersolution is constructed by a composite function of a solution to an ordinary differential equation and a distance function. The results work efficiently in the case where the domain is an exterior or an interior of a convex set.

ELLIPTIC EQUATIONS OF ORDER 2m IN ANNULAR DOMAINS
In this paper we study the existence of positive radial solutions for some semilinear elliptic problems of order 2m in an annulus with Dirichlet boundary conditions. We consider a nonlinearity which is either sublinear or the sum of a sublinear and a superlinear term.
متن کاملA Priori Estimates and Existence for a Class of Fully Nonlinear Elliptic Equations in Conformal Geometry
In this paper we prove the interior gradient and second derivative estimates for a class of fully nonlinear elliptic equations determined by symmetric functions of eigenvalues of the Ricci or Schouten tensors. As an application we prove the existence of solutions to the equations when the manifold is locally conformally flat or the Ricci curvature is positive. Dedicated to the memory of Profess...
متن کاملElliptic equations for measures on infinite dimensional spaces and applications
We introduce and study a new concept of a weak elliptic equation for measures on infinite dimensional spaces. This concept allows one to consider equations whose coefficients are not globally integrable. By using a suitably extended Lyapunov function technique, we derive a priori estimates for the solutions of such equations and prove new existence results. As an application, we consider stocha...

متن کاملProportionality of Components, Liouville Theorems and a Priori Estimates for Noncooperative Elliptic Systems
We study qualitative properties of positive solutions of noncooperative, possibly nonvariational, elliptic systems. We obtain new classification and Liouville type theorems in the whole Euclidean space, as well as in half-spaces, and deduce a priori estimates and existence of positive solutions for related Dirichlet problems. We significantly improve the known results for a large class of syste...
