Proposition 22.1.23F7D709A21AE1

Proposition 22.1.23.F7D709A21AE1 Let $\Gamma ,\Gamma '\in \mathrm{PSH}^{\mathrm{NA}}(X,\theta )$. Assume that $\Gamma \leq \Gamma '$. Then

\[ \operatorname{vol}\Gamma \leq \operatorname{vol}\Gamma '. \]

Proof. It suffices to show that for any Kähler form $\omega $ on $X$, we have

\[ \operatorname{vol}\Gamma ^{\theta +\omega }_{-\infty }\leq \operatorname{vol}\Gamma '{}^{\theta +\omega }_{-\infty }, \]

which is an immediate consequence of theorem 13.13.11. $\square$
