Integral cohomology of certain Picard modular surfaces

Dan Yasaki

摘要:

设Gamma是虚数域k的Picard模群的同余子群,D是相应的对称空间.给出了局部对称空间Gamma \D的积分上同调的一种计算方法.对k=Q(i)和k=Q(sqrt(-3))的情形实现了该方法,并计算了不同Gamma的上同调。

英文摘要:

Let Gamma be a congruence subgroup of the Picard modular group of an imaginary number field k, and let D be the associated symmetric space. We describe a method to compute the integral cohomology of the locally symmetric space Gamma\D. The method is implemented for the case k=Q(i) and k=Q(sqrt(-3)), and the cohomology is computed for various Gamma.
