摘要

研究了固定lc对的两个对数极小模型之间的关系。对于用log MMP构造的lc对的任意两个log极小模型，我们证明了log极小模型的两个小模型可以通过一串flops连接，并且这两个log极小模型具有一些共同的性质。我们还给出了具有不同性质的lc对的两个对数极小模型的例子。

Relations between two log minimal models of log canonical pairs

We study relations between two log minimal models of a fixed lc pair. For any two log minimal models of an lc pair constructed with log MMP, we prove that there are small birational models of the log minimal models which can be connected by a sequence of flops, and the two log minimal models share some properties. We also give examples of two log minimal models of an lc pair which have different properties.
