Consider a normal complex analytic space $X$ and a projective birational resolution $f:Y\rightarrow X$. Let $T$ be a closed positive current of bi-dimension $(p,p)$ on $X$. Is there always a closed positive current $S$ on $Y$ such that $f\_\*S=T$?



Do all closed positive currents lift to a resolution?
I believe the answer is no.


If I am reading the article below by Méo correctly, he shows that if
$\pi : Y \to X$ is the blowup of the polydisc $X=D^m$ along $Z := \{ z\_1 = \dots = z\_k = 0 \}$, and if $k \leq p \leq n-2$, then there exists a closed positive $(p,p)$-current $T$ on $X$ such that $T' := \pi^\* (T|\_{X\setminus Z})$ does not have locally finite mass near $\pi^{-1}(Z)$. If such $S$ exists, then since $\pi$ is a biholomorphism on $Y' := \pi^{-1}(X\setminus Z)$, one would have $S|\_{Y'} = T'$, which would thus have locally finite mass.
