Atypical generic directions in Teichmüller space
Matthew Gentry Durham, Chenxi Wu, Kejia Zhu
Motivated by geometrically capturing generic directions in Teichmüller space -- that is, tracking rays for random walks of the mapping class group -- we use work of Chaika--Masur--…
CAT(0) geometry of complex curve complements and families
Corey Bregman, Anatoly Libgober, Kejia Zhu
Motivated by the question of whether braid groups are CAT(0), we investigate the CAT(0) behavior of fundamental groups of plane curve complements and certain universal families. If…
A note on complex hyperbolic lattices and strict hyperbolization
Kejia Zhu
We study the connection between the fundamental groups of complex hyperbolic manifolds and those of spaces arising from the (relative) strict hyperbolization process due to Charney…
Conditions on the monodromy for a surface group extension to be CAT(0)
Kejia Zhu
In order to determine when surface-by-surface bundles are non-positively curved, Llosa Isenrich and Py give a necessary condition: given a surface-by-surface group with infinit…
Bounds on degrees of covers with injective monodromy in iterated Kodaira Fibrations
Kejia Zhu
Let be an -dimensional iterated Kodaira fibration with fiber of genus and injective monodromy. Llosa Isenrich and Py proved that we can pass to a finite index sub…
