On construction of positive closed currents with prescribed Lelong numbers
Hedi Khedhiri University of Monastir, Monastir, Tunisia
Abstract:
We establish that a sequence (Xk)k∈N of analytic subsets of a domain Ω in Cn, purely dimensioned, can be released as the family of upper-level sets for the Lelong numbers of some positive closed current. This holds whenever the sequence (Xk)k∈N satisfies, for any compact subset L of Ω, the growth condition ∑k∈NCkmes(Xk∩L)<∞. More precisely, we built a positive closed current Θ of bidimension (p,p) on Ω, such that the generic Lelong number mXk of Θ along each Xk satisfies mXk=Ck. In particular, we prove the existence of a plurisubharmonic function v on Ω such that, each Xk is contained in the upper-level set ECk(ddcv).
