Abstract

We show that any set E ⊂ Cⁿ, n ≥ 2, with finite Hausdorff measure Λ_{(log 1/r)-n} (E) < + ∞ is pluripolar. The result is sharp with respect to the measuring function. The new idea in the proof is to combine a construction from potential theory, related to the real variational integral ∫_Ω|∇u|^m, Ω ⊂ R^m, with properties of the pluricomplex relative extremal function for the Bedford-Taylor capacity.
