Hirzebruch曲面上的Kähler-里奇流

The Kähler-Ricci flow on Hirzebruch surfaces

Jian Song, Ben Weinkove

摘要:

研究了Hirzebruch曲面上Kahler-里奇流的度量行为,假设初始度量在自同构群的极大紧子群下不变.我们证明,在Gromov-Hausdorff意义下,流要么收缩到一个点,要么坍缩到$\mathbb{P}^1$,要么收缩到一个例外因子,证实了Feldman-Ilmanen-Knopf的一个猜想。我们还表明,类似的行为举行高维类似物的Hirzebruch表面。

英文摘要:

We investigate the metric behavior of the Kahler-Ricci flow on the Hirzebruch surfaces, assuming the initial metric is invariant under a maximal compact subgroup of the automorphism group. We show that, in the sense of Gromov-Hausdorff, the flow either shrinks to a point, collapses to $\mathbb{P}^1$ or contracts an exceptional divisor, confirming a conjecture of Feldman-Ilmanen-Knopf. We also show that similar behavior holds on higher-dimensional analogues of the Hirzebruch surfaces.
