Provides a description of global invertible functions.
Abstract
In this article, we study the cohomology of some analytic sheaves on the complementary in the projective space of a suitable infinite collection of hyperplane like the Drinfel'd symetric space. In particular, the sheaf of invertible functions on these rigid spaces has no cohomology in degree greater or equal to . This proves the vanishing of the Picard goup and the methods used give a convenient description of the global invertible functions.
