Regularization and Hölder continuity for complex Hessian equations on Hermitian manifolds

Abstract

Let $(M,ω)$ be a compact Hermitian manifold, and let $Γ$ be a symmetric convex cone. We develop a quantitative regularization method for $Γ$-admissible functions. As an application, we prove Hölder continuity for every pluripotential solution of complex $m$-Hessian equations whose right-hand sides belong to $L^p$, for $p>\frac{n}{m}$. These results extend to a more general class of complex Hessian equations satisfying the structural condition used by Guo--Phong--Tong.
