论文摘要
我们证明了代数表面的Belyi定理的类似物。也就是说，如果并且仅在三个打结的二维球体下，可以在数字场上定义任何非符号代数表面。
We prove an analog of Belyi's theorem for the algebraic surfaces. Namely, any non-singular algebraic surface can be defined over a number field if and only it covers the complex projective plane with ramification at three knotted two-dimensional spheres.
