标题： Some results and problems on tournament structure

摘要： 本文是对与如下问题相关的成果和问题的综述：如果 \$G\$ 是一个竞赛图且其色数足够大，那么 \$G\$ 是否包含两个顶点不相交的子竞赛图 \$A,B\$，它们的色数都很大，并且它们之间的所有边都从 \$A\$ 指向 \$B\$？ 我们描述了关于这个问题已知的内容，并报告了在其他几个相关问题上的进展，这些问题涉及竞赛图的着色和支配。 显示英文摘要

摘要： This paper is a survey of results and problems related to the following question: is it true that if G is a tournament with sufficiently large chromatic number, then G has two vertex-disjoint subtournaments A,B, both with large chromatic number, such that all edges between them are directed from A to B? We describe what we know about this question, and report some progress on several other related questions, on tournament colouring and domination.
