Perfect k-Colored Matchings and [Formula: see text] -Gonal Tilings

We derive a simple bijection between geometric plane perfect matchings on 2n points in convex position and triangulations on [Formula: see text] points in convex position. We then extend this bijection to monochromatic plane perfect matchings on periodically k-colored vertices and [Formula: see text...

Sumario:We derive a simple bijection between geometric plane perfect matchings on 2n points in convex position and triangulations on [Formula: see text] points in convex position. We then extend this bijection to monochromatic plane perfect matchings on periodically k-colored vertices and [Formula: see text] -gonal tilings of convex point sets. These structures are related to a generalization of Temperley–Lieb algebras and our bijections provide explicit one-to-one relations between matchings and tilings. Moreover, for a given element of one class, the corresponding element of the other class can be computed in linear time.
