On Kahler extensions of abelian groups
Corey Bregman, Letao Zhang
We show that any Kahler extension of a finitely generated abelian group by a surface group of genus g at least 2 is virtually a product. Conversely, we prove that any homomorphism…

Hyperelliptic graphs and the period mapping on outer space
Corey Bregman, Neil J. Fullarton
The period mapping assigns to each rank n, marked metric graph Gamma a positive definite quadratic form on H_1(Gamma). This defines maps Phi* and Phi on Culler--Vogtmann's outer sp…

Automorphisms and homology of non-positively curved cube complexes
Corey Bregman
We define an integer-valued invariant of special cube complexes called the genus, and prove that having genus one characterizes special cube complexes with abelian fundamental grou…
