These are the videos for the course "Introduction to Fibrations" that I teach at Rhur University Bochum during the Spring semester of 2021.
We define Čech cohomology and prove that a short exact sequence of sheaves induces a long exact sequence in Čech cohomology; this is not an immediate application of the Snake's Lemma. We also characterize the Picard group of a complex manifold M as the first Čech cohomology group of M with values in the sheaf of non-zero holomorphic functions.
