Class Numbers of CM Tori and Components of Unitary Shimura Varieties (II)
Chia-Fu Yu (Academia Sinica)
Abstract:
In these two talks we will introduce the class numbers and Tamagawa numbers of algebraic tori. We will show how to compute these numbers for CM tori and the application to computing the number of connected components of unitary Shimura varieties. This is joint work with Nai-Heng Sheu and Jia-Wei Guo.
