本文用Dwork-Katz方法和形式群律的观点研究了有限域上Calabi-Yau簇的Dwork族成员的单位根的变化.得到了单位根远离Hasse轨迹的近似进解析公式。
We study the variation of the unit roots of members of the Dwork families of Calabi–Yau varieties over a finite field by the method of Dwork–Katz and also from the point of view of formal group laws. Ap-adic analytic formula for the unit roots away from the Hasse locus is obtained.
