Tilings of the Sphere by Edge Congruent Pentagons [PDF]

open access: yes, 2013
We study edge-to-edge tilings of the sphere by edge congruent pentagons, under the assumption that there are tiles with all vertices having degree 3. We develop the technique of neighborhood tilings and apply the technique to completely classify edge ...

Gale-Robinson Sequences and Brane Tilings [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
We study variants of Gale-Robinson sequences, as motivated by cluster algebras with principal coefficients. For such cases, we give combinatorial interpretations of cluster variables using brane tilings, as from the physics literature.

Rhombic Tilings and Primordia Fronts of Phyllotaxis [PDF]

open access: yes, 2017
We introduce and study properties of phyllotactic and rhombic tilings on the cylin- der. These are discrete sets of points that generalize cylindrical lattices.

Tiling the pentagon

open access: yesDiscrete Mathematics, 2000
The authors investigate several possibilities to dissect a convex pentagon into smaller pentagons. In Theorem 1, they show that a convex pentagon \(P\) can always be dissected into \(n\) pentagons which form an edge-to-edge tiling of \(P\), for any \(n\geq 6\). An edge-to-edge tiling of a pentagon \(P\) is called cubic if every vertex of the tiling has

Arctic octahedron in three-dimensional rhombus tilings and related integer solid partitions

open access: yes, 2002
Three-dimensional integer partitions provide a convenient representation of codimension-one three-dimensional random rhombus tilings. Calculating the entropy for such a model is a notoriously difficult problem.

THE CHARACTER OF PLANAR TESSELLATIONS WHICH ARE NOT SIDE-TO-SIDE

open access: yesImage Analysis and Stereology, 2014
This paper studies stationary tessellations and tilings of the plane in which all cells are convex polygons. The focus is on the class of tessellations which are not side-to-side.

Tiling Phosphorene

open access: yesACS Nano, 2014
We present a scheme to categorize the structure of different layered phosphorene allotropes by mapping their non-planar atomic structure onto a two-color 2D triangular tiling pattern. In the buckled structure of a phosphorene monolayer, we assign atoms in "top" positions to dark tiles and atoms in "bottom" positions to light tiles.

Doubly Semiequivelar Maps on Torus and Klein Bottle

open access: yesJournal of Mathematics, 2020
A tiling of the Euclidean plane, by regular polygons, is called 2-uniform tiling if it has two orbits of vertices under the action of its symmetry group. There are 20 distinct 2-uniform tilings of the plane.

Meadows in the Heptgrid and Possible Generalizations [PDF]

open access: yesComputer Science Journal of Moldova
In this paper, we summarize the results about flowers in the heptagrid, the tessellation $(7,3)$ of the hyperbolic plane, results presented for MCU'2024 at Nice, France.
