Discrete rotations and symbolic dynamics
The aim of this paper is to study local configurations issued from discrete rotations. The algorithm of discrete rotations that we consider is the discretized rotation. It simply consists in the composition of a Euclidean rotation with a rounding operation, as studied in [B. Nouvel, E. Rémila, On colorations induced by discrete rotations, in: DGCI, in: LNCS, vol. 2886, 2003, pp. 174–183; B. Nou...
متن کاملDiscrete Geometry and Symbolic Dynamics
The aim of this survey is to illustrate various connections that exist between word combinatorics and arithmetic discrete geometry through the discussion of some discretizations of elementary Euclidean objects (lines, planes, surfaces). We focus on the role played by dynamical systems (toral rotations mainly) that can be associated in a natural way with these discrete structures. We show how cl...
متن کاملSymbolic Dynamics and the Discrete Variational Principle
We show how to construct symbolic dynamics for the class of 2d-dimensional twist mappings generated by piecewise strictly convex/concave generating functions. The method is constructive and gives an eecient way to nd all periodic orbits of these high dimensional symplectic mappings. It is illustrated with the cardioid and the stadium billiard.

امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
Understanding discrete rotations
The concept of rotations in continuous-time, continuousfrequency is extended to discrete-time, discrete-frequency as it applies to the Wigner distribution. As in the continuous domain, discrete rotations are de ned to be elements of the special orthogonal group over the appropriate (discrete) eld. Use of this de nition ensures that discrete rotations will share many of the same mathematical pro...
