Paper

Minimality and nonergodicity on a family of flat surfaces in genus 3, arXiv:0801.0466, January 2008.
Abstract: We prove that a certain family of flat surfaces in genus 3 does not fulfill Veech's Dichotomy. These flat surfaces provide uncountably many minimal but nonergodic directions. The conditions on this family are a combinatorical one and an irrationality condition. The Arnoux-Yoccoz surface fulfills this conditions.
