General origamis and Veech groups of flat surfaces
Shun Kumagai
In this century, a square-tiled translation surface (an origami) is intensively studied as an object with special properties of its translation structure and its …

Calculation of Veech groups and Galois invariants of general origamis
Shun Kumagai
Nontrivial examples of Teichmüller curves have been studied systematically with notions of combinatorics invariant under affine homeomorphisms. An origami (square-tiled surface) in…

A characterization of Veech groups in terms of origamis
Shun Kumagai
Schmithüsen proved in 2004 that the Veech group of an origami is closely related to a subgroup of the automorphism group of the free group . This result is significant in the…
