We consider the complex Monge–Ampère equation on compact
manifolds when the background metric is a Hermitian metric (in complex
dimension 2) or a Hermitian metric satisfying an additional condition (in
higher dimensions). We prove that the Laplacian estimate holds when
is in
for
any
.
As an application, we show that, up to scaling, there exists a unique classical solution
in
for the complex Monge–Ampère equation when
is
in .
