Conway's classification of frieze patterns
WebMar 31, 2024 · Every subpolygon of a Conway-Coxeter frieze yields a frieze with coefficients over the natural numbers. In this paper we give a complete arithmetic criterion for which friezes with coefficients appear as subpolygons of Conway-Coxeter friezes.

WebJun 7, 2024 · One of the first properties of frieze patterns is that every quiddity sequence of a closed integral frieze contains at least two entries equal to 1. Theorem 2 gives a geometric reason for this, since every triangulation contains at least two triangles that are peripheral, i.e., for which two edges are boundary segments.

WebFeb 22, 2024 · Coxeter defined the notion of frieze pattern, and Conway and Coxeter proved that triangulations of polygons are in bijection with integral frieze patterns. We … Websee how frieze patterns with coe cients can be obtained from classic frieze patterns by cutting out subpolygons from the triangulated polygons associated to classic Conway-Coxeter frieze patterns. We address the question of which frieze patterns with coe cients can be obtained in this way and solve this problem completely for triangles.
