A note on the abelianizations of finite-index subgroups of the mapping class group

Andrew Putman

For some $g \geq 3$ , let $Γ$ be a finite index subgroup of the mapping class group of a genus $g$ surface (possibly with boundary components and punctures). An old conjecture of Iv…

The second rational homology group of the moduli space of curves with level structures

Andrew Putman

Let $Γ$ be a finite-index subgroup of the mapping class group of a closed genus $g$ surface that contains the Torelli group. For instance, $Γ$ can be the level $L$ subgroup or the…

The abelianization of the level L mapping class group

Andrew Putman

We calculate the abelianizations of the level $L$ subgroup of the genus $g$ mapping class group and the level $L$ congruence subgroup of the $2 g \times 2 g$ symplectic group for $L$ …
