The Birman--Craggs--Johnson homomorphism and the handlebody Torelli group
Annie Holden
We use the Birman--Craggs--Johnson (BCJ) homomorphism to study the intersection of the handlebody group with the Torelli group and with the Johnson kernel. For genus , we d…

Abelianizations of finite-index subgroups of the handlebody group
Annie Holden
For genus , it is an open question whether the mapping class group of a handlebody contains a finite-index subgroup with nontrivial rational abelianization. In this paper,…
