We studied the arithmetic of Calabi-Yau threefolds with fibration by elliptic curves and/or K3 surfaces. The focus was put on Calabi-Yau threefolds of Delsarte type defined in a weighted projective space over a number field and also on Calabi-Yau threefolds considered by Voisin and Borcea in their construction of mirror symmetry. Taking into account the information of fibrations, we computed the cohomology, zeta functions and L-functions of such Calabi-Yau threefolds. We moreover obtained results on their modularity (automorphy) and on the height of their formal groups.

研究了椭圆曲线和K3曲面上纤维化的Calabi-Yau三重性的算法。重点是定义在数域上的加权射影空间中的Delsarte型Calabi-Yau三重以及Voisin和Borcea在构造镜像对称时考虑的Calabi-Yau三重。考虑到纤维化的信息，我们计算了这类Calabi-Yau三重的上同调，zeta函数和L-函数。此外，我们得到的结果，其模块性（自同构）和高度的正式集团。
