摘要:

我们构造代数几何码从del Pezzo表面,并专注于皮卡德秩1和代码相关联的anticanonical类。我们给出了度为4,5,6的del Pezzo曲面的显式构造,计算了相关反规范码的参数,并研究了它们的自同构.我们获得了具有出色参数的代码,其中一些代码击败了数据库代码表中列出的最知名的代码。

英文摘要:

We construct algebraic geometric codes from del Pezzo surfaces and focus on the ones having Picard rank one and the codes associated to the anticanonical class. We give explicit constructions of del Pezzo surfaces of degree 4, 5 and 6, compute the parameters of the associated anticanonical codes and study their isomorphisms arising from the automorphisms of the surface. We obtain codes with excellent parameters and some of them turn out to beat the best known codes listed on the database codetable.
