The mapping class group of connect sums of $S^{2} \times S^{1}$

Tara Brendle, Nathan Broaddus, Andrew Putman

Let $M_{n}$ be the connect sum of $n$ copies of $S^{2} \times S^{1}$ . A classical theorem of Laudenbach says that the mapping class group $Mod (M_{n})$ is an extension of $\text{Out}…

VIC-modules over noncommutative rings

Andrew Putman, Steven V Sam

For a finite ring $R$ , not necessarily commutative, we prove that the category of $VIC (R)$ -modules over a left Noetherian ring $k$ is locally Noetherian, generalizi…

The high-dimensional cohomology of the moduli space of curves with level structures II: punctures and boundary

Tara Brendle, Nathan Broaddus, Andrew Putman

We give two proofs that appropriately defined congruence subgroups of the mapping class group of a surface with punctures/boundary have enormous amounts of rational cohomology in t…
