Remark 3.10.

Following Zeriahi [40] one can prove that for all α<2/ν⁡(X,ω)\alpha<2/\nu(X,\omega) there exists Cα>0C_{\alpha}>0 such that

Volω​(⋅)≤Cα​Tω​(⋅)α,\text{Vol}_{\omega}(\cdot)\leq C_{\alpha}T_{\omega}(\cdot)^{\alpha},

where ν(X,ω)=sup{ν(φ,x)/φ∈PSH(X,ω),x∈X}\nu(X,\omega)=\sup\{\nu(\varphi,x)\,/\,\varphi\in PSH(X,\omega),x\in X\} and ν⁡(φ,x)\nu(\varphi,x) denotes the Lelong number of φ\varphi at point xx. In particular it follows from proposition 3.8 that ∀φ∈P​S​H​(X,ω)\forall\varphi\in PSH(X,\omega) with supXφ=0\sup_{X}\varphi=0,

Volω​(φ<−t)≤Cα​exp⁡(−α​t),∀t∈ℝ.\text{Vol}_{\omega}(\varphi<-t)\leq C_{\alpha}\exp(-\alpha t),\;\forall t\in\mathbb{R}.

Such inequalities are quite useful in complex dynamics [20],[22] and in the study of the complex Monge-Ampère operator [24], [28].
