Landkreis Emsland () is a district in Lower Saxony, Germany named after the river Ems. It is bounded by (from the north and clockwise) the districts of Leer, Cloppenburg and Osnabrück, the state of North Rhine-Westphalia (district of Steinf ...
, Germany – 4 September 2011) was a German mathematician. He is known for major works on
several complex variables
The theory of functions of several complex variables is the branch of mathematics dealing with complex number, complex-valued functions. The name of the field dealing with the properties of function of several complex variables is called several ...

complex manifold
In differential geometry and complex geometry, a complex manifold is a manifold with an atlas of charts to the open unit disc in \mathbb^n, such that the transition maps are holomorphic.
The term complex manifold is variously used to mean a ...

sheaf theory
In mathematics, a sheaf is a tool for systematically tracking data (such as sets, abelian groups, rings) attached to the open sets of a topological space and defined locally with regard to them. For example, for each open set, the data could ...
