项目摘要
The purpose of this research was to study the arithmetic properties of Calabi-Yau threefolds with mirror symmetry and investigate the relationships between number theory and physics. The main object of this research was Calabi-Yau threefolds over finite fields and number fields. In particular, detailed studies were conducted for Calabi-Yau threefolds in weighted projective spaces and for those having K3 fibrations. Throughout the project, I had collaboration work with Professor Noriko Yui at Queen's University in Ontario, Canada.In every aspect of this project, except for the part concerning the special values of L-series, I was able to obtain results as expected. The results were presented in four seminar/workshop talks and I wrote one accepted paper and three preprints. The following describe details of my results :1.I considered Calabi-Yau threefolds constructed from weighted Delsarte threefolds and those having K3 fibrations, and computed their cohomology groups and the exact form … More of their zeta-functions and L-series.2.The height of the formal groups of Calabi-Yau threefolds was calculated and I refined the known formula for the height of the formal groups. Also, I found many Calabi-Yau threefolds with large height which had not been discovered earlier.3.I considered the effects of mirror symmetry on the zeta-functions and formal groups of Calabi-Yau threefolds. It was found that the mirror symmetry does not have any influence on the formal groups, while it has strong effects on the zeta-functions. This result was used for the calculations of the height of formal groups and for the characterization of zeta-functions. This gives, in fact, an important relationship between number theory and physics.4.I computed the zeta-functions and L-series of some 4-dimensional varieties and compared them with those of threefolds. Consequently, the difference and similarities between these varieties became clear.Finally, I note that my collaboration with Professor Yui was carried out by email and in five intensive meetings in person.

本研究的目的是研究具有镜像对称的Calabi-Yau三倍的算术性质,并探讨数论与物理之间的关系。本研究的主要对象是有限域和数域上的三倍Calabi-Yau。特别是,在加权投影空间中对Calabi-Yau进行了三倍的详细研究,并对那些有K3颤动的人进行了详细研究。在整个项目中,我与加拿大安大略省皇后大学的Noriko Yui教授进行了合作。在这个项目的各个方面,除了关于l系列的特殊值的部分,我都能得到预期的结果。结果在四次研讨会/研讨会上发表,我写了一篇被接受的论文和三篇预印本。以下详细描述了我的结果:我考虑了由加权Delsarte三倍和那些具有K3纤维构成的Calabi-Yau三倍,并计算了它们的上同调群和确切形式…更多的ζ函数和l -级数。计算了Calabi-Yau三倍体的形式群的高度,并对已知的形式群高度公式进行了改进。此外,我还发现了许多以前没有发现的高大的卡拉比-丘三叠。我考虑了镜面对称对ζ函数和三倍Calabi-Yau的形式群的影响。研究发现,镜像对称对形式群没有影响,但对ζ函数有很强的影响。这一结果用于形式群高度的计算和ζ函数的表征。事实上,这说明了数论和物理学之间的重要关系。我计算了一些四维变量的函数和l级数,并将它们与三维变量的函数和l级数进行了比较。因此,这些品种之间的区别和相似之处变得清晰起来。最后,我注意到我与Yui教授的合作是通过电子邮件和五次面对面的密集会议进行的。少
