A characterization of semistable radial solutions of k-Hessian equations
نویسندگان
چکیده
We characterize semistable radial solutions of the equationSk(D2u)=g(u)in B1, where B1 is unit ball Rn, D2u Hessian matrix u,g a positive C1 nonlinearity and Sk(D2u) denotes k-Hessian operator u. This class has been recently introduced by authors. The proofs are new focusing on structure equation directly, thereby improving some previous results.

Local solvability of the k-Hessian equations
In this work, we study the existence of local solutions in R to k-Hessian equation, for which the nonhomogeneous term f is permitted to change the sign or be non negative; if f is C∞ , so is the local solution. We also give a classification for the second order polynomial solutions to the k−Hessian equation, it is the basis to construct the local solutions and obtain the uniform ellipticity of ...
متن کاملComputation of radial solutions of semilinear equations
We express radial solutions of semilinear elliptic equations on Rn as convergent power series in r, and then use Pade approximants to compute both ground state solutions, and solutions to Dirichlet problem. Using a similar approach we have discovered existence of singular solutions for a class of subcritical problems. We prove convergence of the power series by modifying the classical method of...
متن کاملOn Positive Radial Solutions for a Class of Elliptic Equations
A class of elliptic boundary value problem in an exterior domain is considered under some conditions concerning the first eigenvalue of the relevant linear operator, where the variables of nonlinear term f(s, u) need not to be separated. Several new theorems on the existence and multiplicity of positive radial solutions are obtained by means of fixed point index theory. Our conclusions are esse...
