Abstract:We use the deformation methods to obtain the strictly log concavity of solution of a class Hessian equation in bounded convex domain in R3, as an application we get the Brunn-Minkowski inequality for the Hessian eigenvalue and characterize the equality case in bounded strictly convex domain in R3.
Keywords:Constant rank theorem  Hessian equation  Eigenvalue  Brunn-Minkowski inequality
