Symmetries and Reversing Symmetries of Trace Maps
A (discrete) dynamical system may have various symmetries and reversing symmetries, which together form its so-called reversing symmetry group. We study the set of 3D trace maps (obtained from two-letter substitution rules) which preserve the Fricke-Vogt invariant I(x, y, z). This set of dynamical systems forms a group G isomorphic with the projective linear (or modular) group PGl(2, Z ). For s...
متن کاملSymmetries and Reversing Symmetries of Toral Automorphisms
Toral automorphisms, represented by unimodular integer matrices, are investigated with respect to their symmetries and reversing symmetries. We characterize the symmetry groups of GL(n,Z) matrices with simple spectrum through their connection with unit groups in orders of algebraic number fields. For the question of reversibility, we derive necessary conditions in terms of the characteristic po...
متن کاملComputing ODE Symmetries as Abnormal Variational Symmetries
We give a new computational method to obtain symmetries of ordinary differential equations. The proposed approach appears as an extension of a recent algorithm to compute variational symmetries of optimal control problems [Comput. Methods Appl. Math. 5 (2005), no. 4, pp. 387-409], and is based on the resolution of a first order linear PDE that arises as a necessary and sufficient condition of i...

We consider tiling models of \round quasicrystals" which would have diiraction patterns which are fully rotation invariant { rings instead of Bragg peaks. They can be distinguished from glasses by self-similarity of the pattern of radii of the rings.
متن کاملBreaking Symmetries
A well-known result by Palamidessi tells us that πmix (the π-calculus with mixed choice) is more expressive than πsep (its subset with only separate choice). The proof of this result argues with their different expressive power concerning leader election in symmetric networks. Later on, Gorla offered an arguably simpler proof that, instead of leader election in symmetric networks, employed the ...
