Definition 3

. A closed positive (1,1)(1,1)-current TT over a compact complex manifold XX possesses analytic singularities if there exists k∈ℕ>0k\in\mathbb{N}_{>0} such that;
a) the ideal sheaf 𝒥k​T{\cal J}^{kT} is coherent,
b) if μ:X~→X\mu:\tilde{X}\rightarrow X a modification such that μ∗​𝒥k​T=𝒪⁡(−D)\mu^{*}{\cal J}^{kT}={\cal O}(-D), with DD an effective divisor with normal crossing, then μ∗​T=λ⁡[D]+α\mu^{*}T=\lambda[D]+\alpha, with λ∈ℝ>0\lambda\in\mathbb{R}_{>0} and α\alpha smooth.
