$C^{2,\alpha}$ regularities and estimates for nonlinear elliptic and parabolic equations in geometry
Abstract
We give sharp estimates for solutions of some fully nonlinear elliptic and parabolic equations in complex geometry and almost complex geometry, assuming a bound on the Laplacian of the solution. We also prove the analogous results to complex Monge-Amp\`{e}re equations with conical singularities. As an application, we obtain a local estimate for Calabi-Yau equation in almost complex geometry. We also improve the regularities and estimates for viscosity solutions to some uniformly elliptic and parabolic equations. All our results are optimal regarding the H\"{o}lder exponent.
