An elementary proof that vector bundles on $\mathbb P^1$ split

Algebraic Geometry 2011-11-08 v2

Abstract

This paper gives a new elementary proof of the theorem that all vector bundles on P1\mathbb P^1 split into the direct sum of line bundles. The proof is based on the study of divisors associated to germs of sections at the generic point.
