Recently, Kolodziej proved that, on a compact Kähler manifold M, the solutions to the complex Monge–Ampère equation with right-hand side in Lp, p > 1, are Hölder continuous with exponent depending on M and ‖f‖p (see [Math. Ann., 342, 379 (2008)]). Then, by using the regularization techniques from [J. Algebr. Geom., 1, 361 (1992)], the authors of [J. Eur. Math. Soc., 16, 619–647 (2014)] determined the optimal exponent of the solutions. We construct a cover of the compact Kähler manifold M that depends only on the curvature of M. Then, as an application, based on the arguments from [Math. Ann., 342, 379 (2008)], we show that the solutions are Hölder continuous with exponent that depends just on the function f on the right-hand side and the upper bound of the curvature of M.
