Masatoshi Sato

摘要:

利用Riemann θ常数、Schottky θ常数和θ乘子,确定了双无分支覆盖的对称映射类群的阿贝尔化.给出了映射类群的某些有限指数子群的阿贝尔化的下界。

英文摘要:

We determine the abelianization of the symmetric mapping class group of a double unbranched cover using the Riemann theta constant, Schottky theta constant, and the theta multiplier. We also give lower bounds of the abelianizations of some finite index subgroups of the mapping class group.
