Log canonical foliation singularities on surfaces

Yen-An Chen

摘要:

给出了曲面上对数典型叶状奇点的极小分解的例外因子的对偶图的分类。作为一个应用,我们证明了具有良好的对数正则叶状奇异性的叶状曲面满足升链条件和Grauert-Riemenschneider型消灭定理.

英文摘要:

We give a classification of the dual graphs of the exceptional divisors on the minimal resolutions of log canonical foliation singularities on surfaces. For an application, we show the set of foliated minimal log discrepancies for foliated surface triples satisfies the ascending chain condition and a Grauert-Riemenschneider type vanishing theorem for foliated surfaces with good log canonical foliation singularities.
