AG码广义Hamming重量的新下界

New Lower Bounds on the Generalized Hamming Weights of AG Codes

Maria Bras-Amorós, Kwankyu Lee, Albert Vico-Oton

摘要:

给出了不属于数值半群理想的最大整数的一个精确上界,并刻画了达到这个上界的理想。然后利用这个结果,通过所谓的Feng-Rao数,来限制代数几何码的广义Hamming重量。这是进一步发展的埃尔米特码和代码之一的加西亚-施蒂希滕斯塔,以及一些更一般的家庭。

英文摘要:

A sharp upper bound for the maximum integer not belonging to an ideal of a numerical semigroup is given and the ideals attaining this bound are characterized. Then the result is used, through the so-called Feng-Rao numbers, to bound the generalized Hamming weights of algebraic-geometry codes. This is further developed for Hermitian codes and the codes on one of the Garcia-Stichtenoth towers, as well as for some more general families.
