关于曲线到一般型曲面的积的支配有理映射

On dominant rational maps from products of curves to surfaces of general type

Francesco Bastianelli, Gian Pietro Pirola

摘要:

本文研究了从一般类型的曲线到曲面的乘积的一般有限支配有理映射的存在性。本文证明了亏格g>6和g '> 1的两条不同的非常一般曲线的乘积CxD不允许在一般类型的其它曲面上有支配有理映射.

英文摘要:

In this paper we investigate the existence of generically finite dominant rational maps from products of curves to surfaces of general type. We prove that the product CxD of two distinct very general curves of genus g>6 and g'>1 does not admit dominant rational maps on other surfaces of general type.
