设K是代数闭域。本文考虑K上n+ 1 > 3次光滑平面曲线类,它包含三个点P1,P2和P3,使得nP 1 + P2,nP 2 + P3和nP 3 + P1是被三条不同的线切割的因子。对于这样的曲线,我们确定了{P1,P2,P3}上支持的某些特殊因子的维数,以及{P1,P2,P3}的任何子集上的所有纯间隙的显式描述。当K = Fq时,这类曲线,其中包括Hermitian曲线,用于构造具有比Goppa界更好的最小距离的代数几何码。
Let K be an algebraically closed field. In this paper, we consider the class of smooth plane curves of degree n+ 1 > 3 over K, containing three points, P1, P2, and P3, such that nP1 + P2, nP2 + P3, and nP3 + P1 are divisors cut out by three distinct lines. For such curves, we determine the dimension of certain special divisors supported on {P1, P2, P3}, as well as an explicit description of all pure gaps at any subset of {P1, P2, P3}. When K = Fq , this class of curves, which includes the Hermitian curve, is used to construct algebraic geometry codes having minimum distance better than the Goppa bound.
