Straight-line trajectories on the Mucube
Andre Oliveira, Felipe A. Ramírez, Chandrika Sadanand +1
The dynamics of straight line flows on compact half-translation surfaces (surfaces formed by gluing Euclidean polygons edge-to-edge via translations possibly composed with rotation…
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…
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…
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{…
Heegaard splittings and virtually special square complexes
Chandrika Sadanand
We give a new perspective of Heegaard splittings in terms square complexes and Guirardel's notion of a \textit{core} which allows for combinatorial measurement of the obstruction t…
Hyperbolic cone metrics and billiards
Viveka Erlandsson, Christopher J. Leininger, Chandrika Sadanand
A negatively curved hyperbolic cone metric is called rigid if it is determined (up to isotopy) by the support of its Liouville current, and flexible otherwise. We provide a complet…
You can hear the shape of a billiard table: Symbolic dynamics and rigidity for flat surfaces
Moon Duchin, Viveka Erlandsson, Christopher J. Leininger +1
We give a complete characterization of the relationship between the shape of a Euclidean polygon and the symbolic dynamics of its billiard flow. We prove that the only pairs of tab…
Structure on the Top Homology and Related Algorithms
Nissim Ranade, Chandrika Sadanand, Dennis Sullivan
We explore the special structure of the top-dimensional homology of any compact triangulable space of dimension . Since there are no -dimensional cells, the top homol…
Modules with 1-dimensional socle and components of Lusztig quiver varieties in type A
Joel Kamnitzer, Chandrika Sadanand
We study modules with 1-dimensional socle for preprojective algebras for type A quivers. In particular, we classify such modules, determine all homomorphisms between them, and then…
