自同构群与反复正则曲线

Automorphism groups and anti-pluricanonical curves

De-Qi Zhang

摘要:

本文证明了在任意光滑射影有理曲面X上存在一条反多重标准曲线,该曲面X具有零熵或Z型自同构的无限群G。Z(半直积),条件是对(X,G)是最小的。这是由Curtis T. McMullen(2005),并进一步追溯到Marat Gizatullin和Brian Harbourne(1987)。我们还证明了(也许)著名的山雀择一定理的最强形式。

英文摘要:

We show the existence of an anti-pluricanonical curve on every smooth projective rational surface X which has an infinite group G of automorphisms of either null entropy or of type Z . Z (semi-direct product), provided that the pair (X, G) is minimal. This was conjectured by Curtis T. McMullen (2005) and further traced back to Marat Gizatullin and Brian Harbourne (1987). We also prove (perhaps) the strongest form of the famous Tits alternative theorem.
