Factor Maps between Tiling Dynamical Systems Draft—february 1, 2008

چکیده
We show that there is no Curtis-Hedlund-Lyndon Theorem for factor maps between tiling dynamical systems: there are codes between such systems which cannot be achieved by working within a finite window. By considering 1-dimensional tiling systems, which are the same as flows under functions on subshifts with finite alphabets of symbols, we construct a ‘simple’ code which is not ‘local’, a local code which is not simple, and a continuous code which is neither local nor simple.

5 J ul 2 00 2 Yang - Baxter maps and integrable dynamics February 1 , 2008
The hierarchy of commuting maps related to a set-theoretical solution of the quantum Yang-Baxter equation (Yang-Baxter map) is introduced. They can be considered as dynamical analogues of the monodromy and/or transfer-matrices. The general scheme of producing Yang-Baxter maps based on matrix factorisation is discussed in the context of the integrability problem for the corresponding dynamical s...
متن کاملPure Point Diffractive Substitution Delone Sets Have the Meyer Property
We prove that a primitive substitution Delone set, which is pure point diffractive, is a Meyer set. This answers a question of J. C. Lagarias. We also show that for primitive substitution Delone sets, being a Meyer set is equivalent to having a relatively dense set of Bragg peaks. The proof is based on tiling dynamical systems and the connection between the diffraction and dynamical spectra.
متن کاملQuotient cohomology for tiling spaces
We define a relative version of tiling cohomology for the purpose of comparing the topology of tiling dynamical systems when one is a factor of the other. We illustrate this with examples, and outline a method for computing the cohomology of tiling spaces of finite type.
متن کاملThe Z Alpern Multi-tower Theorem for Rectangles: a Tiling Approach
We provide a proof of the Alpern multi-tower theorem for Z d actions. We reformulate the theorem as a problem of measurably tiling orbits of a Z action by a collection of rectangles whose corresponding sides have no non-trivial common divisors. We associate to such a collection of rectangles a special family of generalized domino tilings. We then identify an intrinsic dynamic property of these ...
متن کاملLattices of tilings and stability
Many tiling spaces such as domino tilings of fixed figures have an underlying lattice structure. This lattice structure corresponds to the dynamics induced by flips. In this paper, we further investigate the properties of these lattices of tilings. In particular, we point out a stability property: the set of all the shortest sequences of flips joining to fixed tilings also have a lattice struct...
