# Minimizing entropy for translation surfaces

@inproceedings{Colognese2021MinimizingEF, title={Minimizing entropy for translation surfaces}, author={Paul Colognese and Mark Pollicott}, year={2021} }

In this note we consider the entropy [5] of unit area translation surfaces in the SL(2,R) orbits of square tiled surfaces that are the union of squares, where the singularities occur at the vertices and the singularities have a common cone angle. We show that the entropy over such orbits is minimized at those surfaces tiled by equilateral triangles where the singularities occur precisely at the vertices.

For a translation surface, we define the systole to be the length of the shortest saddle connection. We give a characterization of the maxima of the systole function on a stratum, and give a family…

It is proved that if a function is completely monotonic, then the triangular lattice minimizes its energy per particle among Bravais lattices for any given density, and the global minimality is deduced, i.e., without a density constraint, of a triangular lattICE for some Lennard-Jones-type potentials and attractive-repulsive Yukawa potentials.
