Theorem 5.16.18.B2A67FDA22D2 Let $\varphi \in \mathrm{PSH}(X)$. Let $x\in X$ and $f\in \mathcal{O}_{X,x}$, $f\neq 0$. Then the following are equivalent:

$f\in \mathcal{I}(\varphi )_ x$;

there exists $\epsilon >0$ such that for any prime divisor $E$ over $X$ such that $x$ is contained in the center of $E$ on $X$, we have

5.16.19
\begin{equation} \operatorname{ord}_ E(f)\geq (1+\epsilon ) \nu (\varphi ,E)-A_ X(E). \end{equation}
In case $\varphi $ has analytic singularities and $\pi \colon Y\rightarrow X$ is a log resolution of $\varphi $ (see definition 5.18.7 for the definition) with finitely many exceptional divisors $\{ E_ i\} $ whose centers on $X$ contain $x$, one may replace (5.16.19) by
43490E287BDA
5.16.20
\begin{equation} \operatorname{ord}_{E_ i}(f)> \nu (\varphi ,E_ i)-A_ X(E_ i)\quad \forall i. \end{equation}
Qualification and proof. For the general germ statement, the precise formulation is the local one: divisors range over modifications of a sufficiently small neighborhood on which $f$ is represented. The proved uniform valuative criterion gives exactly
\[f\in\mathcal I(\varphi)_x\quad\Longleftrightarrow\quad\exists\varepsilon>0:\ \operatorname{ord}_Ef+A_X(E)\geq(1+\varepsilon)\nu(\varphi,E)\]
for all such divisors whose centers contain $x$. The same $\varepsilon$ must work for every divisor.
In the analytic-singularity clause, one must test all components of the total pole divisor on the log resolution whose centers contain $x$, including nonexceptional components. Restricting the test to exceptional divisors is false: on $\mathbb C$ take $\varphi=\log|z|^2$ and the identity resolution. There are no exceptional divisors, but $1\notin\mathcal I(\varphi)_0$ since $|z|^{-2}$ is not locally integrable.
Here is the finite test with this correction. On a log resolution write $\varphi\circ\pi=\sum_i a_i\log|s_i|^2+O(1)$ and let $b_i$ be the order of the holomorphic Jacobian along $D_i=\{s_i=0\}$. If $c_i=\operatorname{ord}_{D_i}(f\circ\pi)$, change of variables makes the integrand, up to a bounded factor and a holomorphic residual factor, a product of $|s_i|^{2(c_i+b_i-a_i)}$. At a generic point of each divisor this residual factor is nonzero. The one-variable integral $\int_0^\delta r^{2(c_i+b_i-a_i)+1}\,\mathrm dr$ is finite exactly when $c_i+b_i+1>a_i$. Since the divisor is simple normal crossings, Fubini proves sufficiency for their simultaneous inequalities and the generic-point calculation proves necessity. Thus the test is $\operatorname{ord}_{D_i}f+A_X(D_i)>\nu(\varphi,D_i)$ for all the indicated total pole components. This is also the log-resolution integrability criterion. Resolution itself remains the permitted Hironaka input.
