In this paper we study the extension of currents across small obstacles. Our main results are: 1) Let A be a closed complete pluripolar subset of an open subset Ω of Cn and T be a negative current of bidimension (p,p) on Ω∖A such that ddcT≥−S on Ω∖A for some positive plurisubharmonic current S on Ω. Assume that the Hausdorff measure H2p(A∩¯SuppT)=0. Then ˜T exists. Furthermore, the current R=~ddcT−ddc˜T is negative supported in A. 2) Let u be a positive strictly k-convex function on an open subset Ω of Cn and set A={z∈Ω:u(z)=0}. Let T be a negative current of bidimension (p,p) on Ω∖A such that ddcT≥−S on Ω∖A for some positive plurisubharmonic (or ddc-negative) current S on Ω. If p≥k+1, then ˜T exists. If p≥k+2, ddcS≤0 and u of class C2, then ~ddcT exists and ~ddcT=ddc˜T.Downloads
