Abstract

Let F\mathcal{F} be a Riemann surface foliation on MEM \setminus E, where MM is a complex manifold and EME \subset M is a closed set. Assume that F\mathcal{F} is hyperbolic, i.e., all leaves of the foliation F\mathcal{F} are hyperbolic Riemann surface. Fix a hermitian metric gg on MM. We will consider the Verjovsky's modulus of uniformization map η\eta, which measures the largest possible derivative in the class of holomorphic maps from the unit disk into the leaves of F\mathcal{F}. Various results are known to ensure the continuity of the map η\eta along the transverse directions, with suitable conditions on MM, F\mathcal{F} and EE. For a domain UMU \subset M, let FU\mathcal{F}_{U} be the holomorphic foliation given by the restriction of F\mathcal{F} to the domain UU, i.e., FU\mathcal{F}\vert_{U}. We will consider the modulus of uniformization map ηU\eta_{U} corresponding to the foliation FU\mathcal{F}_{U}, and study its variation when the corresponding domain UU varies in the Caratheodory kernel sense, motivated by the work of Lins Neto--Martins.
