Abstract:Let A be a closed subset of an open subset of C n and T be a negative current on A of bidimension (p, p). Assume that T is psh and A is complete pluripolar such that the Hausdorff measure H 2p (SuppT ∩ A) = 0, then T extends to a negative psh current on . We also show that if T is psh or if dd c T extends to a current with locally finite mass on , then the trivial extension T of T by zero across A exists in both cases: A is the zero set of a k−convex function with k ≤ p − 1 or H 2(p−1) (SuppT ∩ A) = 0.

“…For S = 0 it is proved by Dabbek-Elkhadhara-El Mir in [5], see also Remark 2.3, and is due to Alessandrini-Bassanelli [1,3] when F is an analytic set and dd c T has bounded mass. Under the extra assumption that dT is of order zero, the result was proved by the second author in [20].…”
We define the pull-back operator, associated to a meromorphic transform, on several types of currents. We also give a simple proof to a version of a classical theorem on the extension of currents.

“…The purpose of the second section is to present a generalization of El Mir's theorem [4,8] on the extension of positive currents across a complete pluripolar subset, in the almost complex setting. In the case of closed currents especially, El Mir's theorem had found quite a number of substantial applications for the development of complex analysis during the last 25 years (see [4] for more comments).…”

“…(the argument consists of considering a suitable convergent series ε m u m and extends without difficulty to the almost complex case). Now, we are ready to state the almost complex version of El Mir's theorem: In the case when J is integrable, this reduces to the results of Dabbek et al [4], see also [8] for the closed case. We mention here that the main result of [4] is to prove Theorem 1 in the complex situation without requiring anything on the mass of the current dT .…”
We prove that every almost complex submanifold of an almost complex manifold is locally J -pluripolar. This generalizes a result of Rosay for J -holomorphic submanifolds. Our second main result is an almost complex version of El Mir's theorem for the extension of positive currents across locally complete pluripolar sets. As a consequence, we extend some results proved by Dabbek-Elkhadhra-El Mir and Dinh-Sibony in the standard complex case. We also obtain a version of the well-known results of Federer and Bassanelli for flat and C-flat currents in the almost complex setting.
“…Le cas d'un courant positif fermé est démontré par El Mir-Feki [8], le cas d'un courant négatif plurisousharmonique (S = 0) est démontré par Dabbek, Elkhadhra et El Mir [4], alors que le cas d'un courant positif plurisousharmonique (psh) où son dd c est supposé de masse localement finie est démontré par Dabbek [2] (en choisissant S = dd c T ). …”
