Title: Seymour’s 6-flow theorem – a short proof

Abstract: Tutte conjectured in 1954 that every bridgeless graph has a nowhere-zero 5-flow. In 1982, Seymour showed that it is true when 5 is replaced with 6. In this talk, I present a short variation of Seymour’s proof. This work is joint with Matt DeVos.
