Local Rules for Computable Planar Tilings [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2012
Aperiodic tilings are non-periodic tilings characterized by local constraints. They play a key role in the proof of the undecidability of the domino problem (1964) and naturally model quasicrystals (discovered in 1982).

Ammann Tilings in Symplectic Geometry [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2013
In this article we study Ammann tilings from the perspective of symplectic geometry. Ammann tilings are nonperiodic tilings that are related to quasicrystals with icosahedral symmetry.

Bounded Wang tilings with integer programming and graph-based heuristics [PDF]

open access: yesScientific Reports, 2023
Wang tiles enable efficient pattern compression while avoiding the periodicity in tile distribution via programmable matching rules. However, most research in Wang tilings has considered tiling the infinite plane.

Generalized Dyck tilings (Extended Abstract) [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2014
Recently, Kenyon and Wilson introduced Dyck tilings, which are certain tilings of the region between two Dyck paths. The enumeration of Dyck tilings is related with hook formulas for forests and the combinatorics of Hermite polynomials. The first goal of

The Crossing Number of Hexagonal Graph H3,n in the Projective Plane

open access: yesDiscussiones Mathematicae Graph Theory, 2022
Thomassen described all (except finitely many) regular tilings of the torus S1 and the Klein bottle N2 into (3,6)-tilings, (4,4)-tilings and (6,3)-tilings.

Geometry of Multiprimary Display Colors II: Metameric Control Sets and Gamut Tiling Color Control Functions

open access: yesIEEE Access, 2021
Multiprimary displays reproduce colors by using combinations of four or more lights that are referred to as primaries. A display control vector defines the relative intensities of the primaries and determines the rendered color. For multiprimary displays,

Structure of spaces of rhombus tilings in the lexicograhic case [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2005
Rhombus tilings are tilings of zonotopes with rhombohedra. We study a class of \emphlexicographic rhombus tilings of zonotopes, which are deduced from higher Bruhat orders relaxing the unitarity condition.

Dyck tilings, linear extensions, descents, and inversions [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2012
Dyck tilings were introduced by Kenyon and Wilson in their study of double-dimer pairings. They are certain kinds of tilings of skew Young diagrams with ribbon tiles shaped like Dyck paths.

Dihedral f-tilings of the sphere by rhombi and triangles [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2005
We classify, up to an isomorphism, the class of all dihedral f-tilings of S^2, whose prototiles are a spherical triangle and a spherical rhombus. The equiangular case was considered and classified in Ana M. Breda and Altino F.

Isotopic tiling theory for hyperbolic surfaces [PDF]

open access: yes, 2020
In this paper, we develop the mathematical tools needed to explore isotopy classes of tilings on hyperbolic surfaces of finite genus, possibly nonorientable, with boundary, and punctured.
