### Description

The aim of this lecture is to give a first introduction into Complex differential geometry, with a special emphasis on vector bundles. It is aimed at students with a basic knowledge of Algebraic Geometry that want to learn more about vector bundles from a differential geometric viewpoint. We will introduce the basic tools of complex differential geometry and try to understand how they relate to concepts in Algebraic Geometry such as characteristic classes, ampleness and stability.### Preliminary list of contents:

complex manifolds and holomorphic vector bundles, Kähler manifolds, Lie groups, principal bundles, connections in principal bundles, characteristic classes via curvature forms, especially Chern classes, if time permits: self-dual connections and relations to algebro-geometric stability.
