Approximation des fonctions lisses sur certaines laminations

Abstract

We show that on a Riemann surface lamination locally embedded in ${\mathbb{C}}^2$, $C^1$ functions (in the sense of the $C^1$ structure of the lamination) are uniform limits of ambient $C^1$ functions, with $L^p$ control on the derivatives along the leaves. This implies that locally in $C^2$, a (1,1) positive closed current dominated by a uniformly laminar current is itself uniformly laminar.
