Highly edge-connected regular graphs without large factorizable subgraphs

Combinatorics 2023-04-18 v1

Abstract

We construct highly edge-connected rr-regular graph which do not contain r2r-2 pairwise disjoint perfect matchings. The results partially answer a question stated by Thomassen [Factorizing regular graphs, J. Comb. Theory Ser. B (2019), https://doi.org/10.1016/j.jctb.2019.05.002 (article in press)].
