Conway's classification of frieze patterns
Did you know?
WebA Conway-Coxeter frieze pattern is a frieze pattern with coefficients over Z>0 with ci,i+1 = 1 for all i ∈ Z. A classic result of Conway and Coxeter states that these frieze patterns are in bijection with triangulations of regular polygons, see [1]. (2) There is a close connection between frieze patterns and Fomin and Zelevinsky’s cluster ... WebMathematician John Conway created names that relate to footsteps for each of the frieze groups. According to Conway, F 1 is also called a HOP. The second frieze group, F 2, …

WebSubpolygons in Conway–Coxeter frieze patterns. Algebraic Combinatorics, Volume 4 (2024) no. 4, pp. 741-755. Friezes with coefficients are maps assigning numbers to the edges and diagonals of a regular polygon such that all Ptolemy relations for crossing diagonals are satisfied. Among these, the classic Conway–Coxeter friezes are the ones ... WebAug 15, 2024 · From a geometric point of view, there are 7 types of frieze patterns and 17 types of wallpaper patterns (Conway and Huson 2002).In this article, the Korean traditional frieze and wallpaper patterns for each type are presented, and their locations are shown in the map (Fig.1) by Roman characters.For example, the frieze pattern of type p1(∞∞) …
WebJun 17, 2024 · In this survey article we explain the intricate links between Conway-Coxeter friezes and cluster combinatorics. More precisely, we provide a formula, relying solely on the shape of the frieze, describing how each individual entry in the frieze changes under cluster mutation. Moreover, we provide a combinatorial formula for the number of submodules of …
