Holomorphic factorization of vector bundle automorphisms
We prove that any null-homotopic special holomorphic vector bundle automorphism of a holomorphic rank 2 vector bundle E over a Stein space X can be written as a finite product of unipotent holomorphic vector bundle automorphisms as well as a finite product of exponentials.
