Topology of Crystallographic Tiles

چکیده
We study self-affine tiles which tile the n-dimensional real vector space with respect to a crystallographic group. First we define classes of graphs that allow to determine the neighbors of a given tile algorithmically. In the case of plane tiles these graphs are used to derive a criterion for such tiles to be homeomorphic to a disk. As particular application, we will solve a problem of Gelbrich, who conjectured that certain examples of tiles which tile R with respect to the ornament group p2 are homeomorphic to a disk.

Local and global topology preservation in locally finite sets of tiles
This paper deals with sets V of tiles (compact, convex sets) in R. Tiles are a generalization of pixels or voxels (in R or R); they can have arbitrary shapes and are allowed to overlap. The union of all the tiles of V is denoted by U(V). The neighborhood N-p(P) of a tile P is the union of the tiles of V that intersect V. P is called simple if deletion of P from V does not change the topology (i...
متن کاملPacking Square Tiles into One Texture
This paper deals with the packing of square tiles of the same size into one texture. Texture size is constrained by the graphics hardware. In particular, width and height resolutions must be powers of two. To cover the whole texture and avoid space loss, common schemes pack a number of tiles that is a power of two. We show that numbers of tiles like 5, 13, 17, 25, 34 and others can also be reac...
متن کاملTopology of (some) Tiling Spaces without Finite Local Complexity
A basic assumption of tiling theory is that adjacent tiles can meet in only a finite number of ways, up to rigid motions. However, there are many interesting tiling spaces that do not have this property. They have “fault lines”, along which tiles can slide past one another. We investigate the topology of a certain class of tiling spaces of this type. We show that they can be written as inverse ...
متن کاملHexagonal Parquet Tilings k - Isohedral Monotiles with Arbitrarily Large k
The interplay between local constraints and global structure of mathematical and physical systems is both subtle and important. The macroscopic physical properties of a system depend heavily on its global symmetries, but these are often difficult to predict given only information about local interactions between the components. A rich history of work on tilings of the Euclidean plane and higher...
متن کاملCrystallographic Topology 2 : Overview and Workin
This overview describes an application of contemporary geometric topology and stochastic process concepts to structural crystallography. In this application, crystallographic groups become orbifolds, crystal structures become Morse functions on orbifolds, and vibrating atoms in a crystal become vector valued Gaussian measures with the Radon-Nikodym property. Intended crystallographic beneets in...
