摘要p-adic超几何函数是经典的Gauss超几何函数在有限域上的模拟,与许多数论问题都有联系.设Fq是q元有限域,λ∈Fq,n为正整数.本文研究了Dwork超曲面Dλn:x1n+x2n+…+xnn=nλx1x2…xn及其推广形式上的Fq-有理点,并在n与q(q-1)互素时给出了由p-adic超几何函数表示的各种Fq-有理点个数的公式,从而修正和改进了Barman与Goodson等人的结论. | | 服务 | | | 加入引用管理器 | | E-mail Alert | | RSS | 收稿日期: 2019-07-17 | | 基金资助:国家自然科学基金资助项目(11871291);宁波市自然科学基金资助项目(2019A610035)
