Tiling of Hyperbolic Surface by Multiple Tiles

Chunlin Li, Erxiao Wang, Wu Jie +1

Tilings of a surface of negative Euler characteristic by n-gons with n\ge 7 is a finite problem. We develop the algorithm for finding all the tilings for fixed number of tiles and…

Side-to-side Tiling of the Sphere by Congruent Curvilinear Triangles

Keyi Jin, Linming Lu, Erxiao Wang +2

The edge-to-edge tilings of the sphere by congruent polygons, where all edges are straight, have been completely classified. We classify the curvilinear version of the similar tria…

Tiling of Hyperbolic Surface by a Single Tile

Chunlin Li, Erxiao Wang, Jie Wu +1

Tilings of a surface of negative Euler characteristic by n-gons with n\ge 7 is a finite problem. One extreme of the finite problem is single tile tilings. We develop the algorithm…

Hexagonal Tiling of the Plane

Ze Zhu, Erxiao Wang, Min Yan

Since the thesis of K. Reinhardt in 1918, it is well known that there are exactly three types of convex hexagons that can tile the plane. However, the proof of the fact is far from…

Tilings of Flat Tori by Congruent Hexagons

Xinlu Yu, Erxiao Wang, Min Yan

Convex hexagons that can tile the plane have been classified into three types. For the generic cases (not necessarily convex) of the three types and two other special cases, we cla…

Tilings of the sphere by congruent quadrilaterals III: edge combination with general angles

Yixi Liao, Pinren Qian, Erxiao Wang +1

Edge-to-edge tilings of the sphere by congruent quadrilaterals are completely classified in a series of three papers. This last one classifies the case of -quadrilaterals wit…

Tilings of the sphere by congruent quadrilaterals II: edge combination with rational angles

Yixi Liao, Erxiao Wang

Edge-to-edge tilings of the sphere by congruent quadrilaterals are completely classified in a series of three papers. This second one applies the powerful tool of trigonometric Dio…

Tilings of the sphere by congruent quadrilaterals I: edge combination

Yixi Liao, Pinren Qian, Erxiao Wang +1

The edge-to-edge tilings of the sphere by congruent quadrilaterals of Type are classified as classes: a sequence of two-parameter families of -layer earth map tiling…

Moduli Spaces of Pentagonal Subdivision Tilings

Jinjin Liang, Erxiao Wang, Min Yan

Pentagonal subdivision gives three families of edge-to-edge tilings of the sphere by congruent pentagons. Each family forms a two dimensional moduli. We describe the moduli in deta…

Tilings of the Sphere by Congruent Pentagons III: Edge Combination

Yohji Akama, Erxiao Wang, Min Yan

There are exactly eight edge-to-edge tilings of the sphere by congruent equilateral pentagons: three pentagonal subdivision tilings with 12, 24, 60 tiles; four earth map tilings wi…
