Theorem 5.27.5 (Mixed Monge–Ampère inequality).DBC85A3C1608 Let $U\subset \mathbb C^ n$ be a domain, and let $\beta $ be its Euclidean Hermitian form. Let $a,b$ be locally bounded plurisubharmonic functions on $U$, and let $f,g$ be nonnegative measurable functions on $U$ with

\[ (\mathrm{dd}^{\mathrm{c}}a)^ n\geq f\beta ^ n, \qquad (\mathrm{dd}^{\mathrm{c}}b)^ n\geq g\beta ^ n. \]

Then, for $0\leq k\leq n$,

\[ (\mathrm{dd}^{\mathrm{c}}a)^ k\wedge (\mathrm{dd}^{\mathrm{c}}b)^{n-k} \geq f^{k/n}g^{(n-k)/n}\beta ^ n. \]
