摘要:

一个图称为唯一列表可着色的,如果它允许一个列表分配,导致一个唯一的列表着色。我们研究唯一列表可着色图的颜色使用的数量上的限制。在这种方法中,我们推广了一个定理,唯一的2-列表着色图的特点。本文引入了图的唯一色数表,并对它作了一个猜想,它是著名的Brooks定理的推广。

英文摘要:

A graph is called to be uniquely list colorable, if it admits a list assignment which induces a unique list coloring. We study uniquely list colorable graphs with a restriction on the number of colors used. In this way we generalize a theorem which characterizes uniquely 2-list colorable graphs. We introduce the uniquely list chromatic number of a graph and make a conjecture about it which is a generalization of the well known Brooks' theorem.
