Asymptotic behavior of solutions of fully nonlinear equations over exterior domains

In this paper, we consider the asymptotic behavior at infinity of solutions of a class of fully nonlinear elliptic equations F (D2u) = f (x) over exterior domains, where the Hessian matrix (D2u) tends to some symmetric positive definite matrix at infinity and f (x) = O(|x|−t ) at infinity with sharp condition t > 2. Moreover, we also obtain the same result if (D2u) is only very close to some symmetric positive definite matrix at infinity. 2020 Mathematics Subject Classification. 35J60, 35B40.
