All regular multigraphs of even order and high degree are 1-factorable
The electronic journal of combinatorics, Tome 8 (2001) no. 1
Plantholt and Tipnis (1991) proved that for any even integer $r$, a regular multigraph $G$ with even order $n$, multiplicity $\mu(G) \leq r$ and degree high relative to $n$ and $r$ is 1-factorable. Here we extend this result to include the case when $r$ is any odd integer. Häggkvist and Perković and Reed (1997) proved that the One-factorization Conjecture for simple graphs is asymptotically true. Our techniques yield an extension of this asymptotic result on simple graphs to a corresponding asymptotic result on multigraphs.
