Rotation $r$-graphs

Combinatorics 2023-04-26 v1

Abstract

We study rotation rr-graphs and show that for every rr-graph GG of odd regularity there is a simple rotation rr-graph GG' such that GG can be obtained form GG' by a finite number of 22-cut reductions. As a consequence, some hard conjectures as the (generalized) Berge-Fulkerson Conjecture and Tutte's 3- and 5-flow conjecture can be reduced to rotation rr-graphs.
