On a domain of the n-dimensional Euclidean space, and for an integer $k = 1, \dotsc , n$, the $k$-Hessian equations are fully nonlinear elliptic equations for $k \gt 1$ and consist of the Poisson equation for $k = 1$ and the Monge–Ampère equation for $k = n$. We analyze for smooth non-degenerate solutions a $9$-point finite difference scheme. We prove that the discrete scheme has a locally unique solution with a quadratic convergence rate. In addition we propose new iterative methods which are numerically shown to work for non smooth solutions. A connection of the latter with a popular Gauss–Seidel method for the Monge–Ampère equation is established and new Gauss–Seidel type iterative methods for $2$-Hessian equations are introduced.
