我们给出了一个最小度的条件,足以确保存在的分数Kr -分解的平衡r-部图(受一些进一步的简单的必要条件)。这推广了Barber,Lo,Kühn,Osthus和作者最近研究的无部问题,以及Bowditch和Dukes最近研究的3部分式K3-分解问题.将我们的结果与Barber,Kühn,Lo,Osthus和Taylor最近的工作相结合,这给出了一个最小度条件,足以确保在平衡r-部图中存在(非分数)Kr -分解(服从相同的简单必要条件)。
We give a minimum degree condition sufficient to ensure the existence of a fractional Kr -decomposition in a balanced r-partite graph (subject to some further simple necessary conditions). This generalizes the non-partite problem studied recently by Barber, Lo, Kühn, Osthus and the author, and the 3-partite fractional K 3-decomposition problem studied recently by Bowditch and Dukes. Combining our result with recent work by Barber, Kühn, Lo, Osthus and Taylor, this gives a minimum degree condition sufficient to ensure the existence of a (non-fractional) Kr -decomposition in a balanced r-partite graph (subject to the same simple necessary conditions).
