Modulus of continuity of solutions to complex Hessian equations

Abstract

We give a sharp estimate of the modulus of continuity of the solution to the Dirichlet problem for the complex Hessian equation of order $m$ ($1 \leq m \leq n$) with a continuous right hand side and a continuous boundary data in a bounded strongly $m$-pseudoconvex domain \Om \Subset \C^n. Moreover when the right hand side is in L^p(\Om) , for some $p > n/m$ and the boundary value function is $C^{1,1}$ we prove that the solution is H\"older continuous.Comment: We prove the H\"older continuity of the solution when the right hand side is in $L^p$ for $p>1$ without any condition on the growth near the boundar
