Horocycle flow orbit closures Lindsey, Kathryn


For any flat surface, the closure of its orbit under the horocycle flow in almost any direction is equal to its $SL(2, \mathbb R)$ orbit closure. I will sketch the proof of this result as well as present a characterization of lattice surfaces in terms of minimal sets for the horocycle flow. These results are joint work with Jon Chaika.
