一般曲线的二阶高斯映射的秩

The rank of the 2nd Gaussian map for general curves

Alberto Calabri, Ciro Ciliberto, Rick Miranda

摘要:

证明了对于亏格为g的一般曲线,当g <= 17时,第二高斯映射是单射的,当g >= 18时,第二高斯映射是满射的.证明依赖于研究亏格g的一般曲线退化为一般稳定二元曲线,即两条相交于g+1点的有理曲线的并时,第二高斯映射的极限.

英文摘要:

We prove that, for the general curve of genus g, the 2nd Gaussian map is injective if g <= 17 and surjective if g >= 18. The proof relies on the study of the limit of the 2nd Gaussian map when the general curve of genus g degenerates to a general stable binary curve, i.e. the union of two rational curves meeting at g+1 points.
