Abstract: In the analytic setting there is a big difference between the local and global framework. The local case is very similar to the algebraic one because the ambient has more or less the same good properties and one can use similar tools. In the global case several hidden and deeper obstructions appear: so the approach is very different. In the first talk we shortly describe the approach given by Forster in '64 to get a Nullstellensatz for Stein algebras i.e. the algebras of global sections of a Stein space.
