Realizing groups as symmetries of infinite translation surfaces
Mauro Artigiani, Anja Randecker, Chandrika Sadanand +2
We provide a complete classification of groups that can be realized as isometry groups of a translation surface with non-finitely generated fundamental group and no planar ends…

Veech groups of covers of the Chamanara surface
Mauro Artigiani, Anja Randecker, Chandrika Sadanand +2
We study finite abelian covers of the Chamanara surface, an example of a finite-area infinite translation surface with interesting dynamics and a large Veech group. Specifically, t…

Flip graph and arc complex finite rigidity
Chandrika Sadanand, Emily Shinkle
A subcomplex of a cell complex is called \emph{rigid} with respect to another cell complex if every injective simplicial map $λ:\mathcal…
