We show that the set of affine equivalence classes of lattice surfaces with a fixed positive lower bound for the areas of triangles is finite and we obtain explicit bounds on its cardinality. We deduce several other characterizations of the lattice property.", "revisions": [ { "version": "v1", "updated": "2008-09-22T15:48:09.000Z" } ], "analyses": { "keywords": [ "lattice surfaces", "characterizations", "lattice property", "affine equivalence classes", "affine triangles" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008arXiv0809.3729S" } } }
