在$\mathbb P^5$中实现伪射影平面为25次曲面

Realizing a Fake Projective Plane as a Degree 25 Surface in $\mathbb P^5$

Lev Borisov, Zachary Lihn

摘要:

伪射影平面是具有与通常的射影平面相同的贝蒂数的光滑复曲面。最近的显式构造的假射影平面嵌入他们通过其双规范嵌入在$\mathbb P^9$。本文研究了Keum的伪射影平面$(a=7, p=2, \{7\}, D_3 2_7)$,并利用\cite{Borisov}的方程构造了伪射影平面在$\mathbb P^5$中的嵌入.我们还简化了$\mathbb P^9$中定义伪射影平面的84个三次方程。

英文摘要:

Fake projective planes are smooth complex surfaces of general type with Betti numbers equal to that of the usual projective plane. Recent explicit constructions of fake projective planes embed them via their bicanonical embedding in $\mathbb P^9$. In this paper, we study Keum's fake projective plane $(a=7, p=2, \{7\}, D_3 2_7)$ and use the equations of \cite{Borisov} to construct an embedding of fake projective plane in $\mathbb P^5$. We also simplify the 84 cubic equations defining the fake projective plane in $\mathbb P^9$.
