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.
ii Summary Every closed oriented surface S of genus g ≥ 2 can be endowed with a non-unique hyperbolic metric. By the celebrated Uniformization Theorem, hyperbolic and complex structures on S are in one-to-one correspondence. A question that arises is: Can we parametrize the complex structures in a nice way? This question brings us to Teichmüller theory.… (More)
Metalocene carboxylic acids labeled with 59Fe or 103Ru were administered to mice and the organ distributions and amounts of label excreted were determined. Both metalocenes were excreted approximately 90 times faster than the respective inorganic chlorides 59FeCl3 or 103RuCl3. The metalocenes showed an extremely high kidney-to-muscle ratio (up to 1,000).… (More)
