本文研究有限域上尖超椭圆曲线同构类的个数。我们讨论亏格为4的有限域具有奇特征的情形。计算同构类的数量。这个数可以表示为q的7次多项式,其中q是有限域的阶数。所得结果在分类问题和超椭圆曲线密码体制中有应用。
This paper is devoted to computing the number of isomorphism classes of pointed hyperelliptic curves over finite fields. We deal with the genus-4 case and the finite fields are of odd characteristic. The number of isomorphism classes is computed. This number can be represented as a polynomial in q of degree 7, where q is the order of the finite field. The results have applications in the classification problems and in the hyperelliptic curve cryptosystems.
