Veech Groups and Translation Coverings

Veech Groups and Translation Coverings PDF Author: Finster, Myriam
Publisher: KIT Scientific Publishing
ISBN: 3731501805
Category : Mathematics
Languages : en
Pages : 154

Book Description
A translation surface is obtained by taking plane polygons and gluing their edges by translations. We ask which subgroups of the Veech group of a primitive translation surface can be realised via a translation covering. For many primitive surfaces we prove that partition stabilising congruence subgroups are the Veech group of a covering surface. We also address the coverings via their monodromy groups and present examples of cyclic coverings in short orbits, i.e. with large Veech groups.

Dynamical Systems: From Crystal To Chaos, Conference In Honor Of Gerard Rauzy On His 60th Birthday PDF Author: J-m Gambaudo
Publisher: World Scientific
ISBN: 9814493627
Category : Science
Languages : en
Pages : 321

Book Description
This book focuses on the interactions between discrete and geometric dynamical systems, and between dynamical systems and theoretical physics and computer science. Accordingly, the contributions revolve around two main topics: (1) interaction between geometric and symbolic systems, with emphasis on tiling problems for quasicrystals, substitutions and their multidimensional generalizations, geodesic and horocycle flow, adic systems; (2) dynamical systems: geometry and chaos, with special interest in smooth ergodic theory, statistical and multifractal properties of chaotic systems, stability and turbulence in extended complex systems.

Translation Surfaces

Translation Surfaces PDF Author: Jayadev S. Athreya
Publisher: American Mathematical Society
ISBN: 1470476770
Category : Mathematics
Languages : en
Pages : 195

Book Description
This textbook offers an accessible introduction to translation surfaces. Building on modest prerequisites, the authors focus on the fundamentals behind big ideas in the field: ergodic properties of translation flows, counting problems for saddle connections, and associated renormalization techniques. Proofs that go beyond the introductory nature of the book are deftly omitted, allowing readers to develop essential tools and motivation before delving into the literature. Beginning with the fundamental example of the flat torus, the book goes on to establish the three equivalent definitions of translation surface. An introduction to the moduli space of translation surfaces follows, leading into a study of the dynamics and ergodic theory associated to a translation surface. Counting problems and group actions come to the fore in the latter chapters, giving a broad overview of progress in the 40 years since the ergodicity of the Teichmüller geodesic flow was proven. Exercises are included throughout, inviting readers to actively explore and extend the theory along the way. Translation Surfaces invites readers into this exciting area, providing an accessible entry point from the perspectives of dynamics, ergodicity, and measure theory. Suitable for a one- or two-semester graduate course, it assumes a background in complex analysis, measure theory, and manifolds, while some familiarity with Riemann surfaces and ergodic theory would be beneficial.

Quasiconformal Mappings, Riemann Surfaces, and Teichmuller Spaces

Quasiconformal Mappings, Riemann Surfaces, and Teichmuller Spaces PDF Author: Yunping Jiang
Publisher: American Mathematical Soc.
ISBN: 0821853406
Category : Mathematics
Languages : en
Pages : 386

Book Description
This volume contains the proceedings of the AMS Special Session on Quasiconformal Mappings, Riemann Surfaces, and Teichmuller Spaces, held in honor of Clifford J. Earle, from October 2-3, 2010, in Syracuse, New York. This volume includes a wide range of papers on Teichmuller theory and related areas. It provides a broad survey of the present state of research and the applications of quasiconformal mappings, Riemann surfaces, complex dynamical systems, Teichmuller theory, and geometric function theory. The papers in this volume reflect the directions of research in different aspects of these fields and also give the reader an idea of how Teichmuller theory intersects with other areas of mathematics.

Geometry and topology of wild translation surfaces

Geometry and topology of wild translation surfaces PDF Author: Randecker, Anja
Publisher: KIT Scientific Publishing
ISBN: 3731504561
Category : Mathematics
Languages : en
Pages : 162

Book Description
A translation surface is a two-dimensional manifold, equipped with a translation structure. It can be obtained by considering Euclidean polygons and identifying their edges via translations. The vertices of the polygons form singularities if the translation structure can not be extended to them. We study translation surfaces with wild singularities, regarding the topology (genus and space of ends), the geometry (behavior of the singularities), and how the topology and the geometry are related.

Monodromy Representations and Lyapunov Exponents of Origamis

Monodromy Representations and Lyapunov Exponents of Origamis PDF Author: André Kappes
Publisher: KIT Scientific Publishing
ISBN: 3866447515
Category : Technology & Engineering
Languages : en
Pages : 154

Book Description
Origamis are translation surfaces obtained by gluing finitely many unit squares and provide an easy access to Teichmüller curves. In particular, their monodromy represenation can be explicitely determined. A general principle for the decomposition of this represenation is exhibited and applied to examples. Closely connected to it is a dynamical cocycle on the Teichmüller curve. It is shown that its Lyapunov exponents, otherwise inaccessible, can be computed for a subrepresentation of rank two.

Twisted Teichmüller Curves

Twisted Teichmüller Curves PDF Author: Christian Weiß
Publisher: Springer
ISBN: 3319040758
Category : Mathematics
Languages : en
Pages : 177

Book Description
These notes introduce a new class of algebraic curves on Hilbert modular surfaces. These curves are called twisted Teichmüller curves, because their construction is very reminiscent of Hirzebruch-Zagier cycles. These new objects are analyzed in detail and their main properties are described. In particular, the volume of twisted Teichmüller curves is calculated and their components are partially classified. The study of algebraic curves on Hilbert modular surfaces has been widely covered in the literature due to their arithmetic importance. Among these, twisted diagonals (Hirzebruch-Zagier cycles) are some of the most important examples.
