Transformed flips in triangulations and matchings

Oswin Aichholzer, Lukas Andritsch, Karin Baur +1

Plane perfect matchings of $2 n$ points in convex position are in bijection with triangulations of convex polygons of size $n + 2$ . Edge flips are a classic operation to perform local…

The boundary algebra of a GL $_{m}$ -dimer

Lukas Andritsch

We consider GL $_{m}$ -dimers of triangulations of regular convex $n$ -gons, which give rise to a dimer model with boundary $Q$ and a dimer algebra $Λ_{Q}$ . Let $e_{b}$ be the sum of the id…

A note on friezes of type $Λ_{p}$

Lukas Andritsch

A frieze is an array of numbers obeying the unimodular rule. Coxeter showed that a frieze with integer entries corresponds to a triangulation. Recently, Holm and Jørgenson introduc…
