在文献[2,3]中,一般类型的simply connected复曲面的Chern斜率是稠密的

Chern slopes of simply connected complex surfaces of general type are dense in [2,3]

Xavier Roulleau, Giancarlo Urzúa

摘要:

证明了对任意个数的$r$在$[2,3]$中存在自旋(或非自旋最小)一般类型$X$的单连通复曲面,其中$c_1^2(X)/c_2(X)$任意接近于$r$ .特别是,这表明存在一般类型的简单连接表面任意接近Bogomolov-Miyaoka-Yau线。另外,我们证明了对任意$r \in [1,3]$和任意整数$q\geq 0$,存在一般型$X$的极小复曲面,其中$c_1^2(X)/c_2(X)$任意接近$r$,且$π_1(X)$同构于亏格为$q$的紧致Riemann曲面的基本群.

英文摘要:

We prove that for any number $r$ in $[2,3]$, there are spin (resp. non-spin minimal) simply connected complex surfaces of general type $X$ with $c_1^2(X)/c_2(X)$ arbitrarily close to $r$. In particular, this shows the existence of simply connected surfaces of general type arbitrarily close to the Bogomolov-Miyaoka-Yau line. In addition, we prove that for any $r \in [1,3]$ and any integer $q\geq 0$, there are minimal complex surfaces of general type $X$ with $c_1^2(X)/c_2(X)$ arbitrarily close to $r$, and $π_1(X)$ isomorphic to the fundamental group of a compact Riemann surface of genus $q$.
