Cluster pictures for Hitchin fibers of rank two Higgs bundles
Sina Zabanfahm
Let be a degree two Galois cover of smooth curves over a local field of odd characteristic. Assuming that has good reduction, we describe a semi-st…

Imploded cross-sections
Lisa Jeffrey, Sina Zabanfahm
In this survey article, we describe imploded cross-sections, which were developed in order to solve the problem that the cross-section of a Hamiltonian -space is usually not sym…

Automorphisms acting on the left-orderings of a bi-orderable group
Adam Clay, Sina Zabanfahm
We generalize a result of T. Koberda by showing that the natural action of the automorphism group on the space of left-orderings is faithful for all nonabelian bi-orderable groups…
