A bijection between triangulations and $312$ -avoiding permutations

Alon Regev

We define a bijection between triangulations of a convex polygon and $312$ -avoiding permutations through the process of "ear-clipping". This bijection is then used to obtain a bije…

Triangulations with few ears: symmetry classes and disjointness

Andrei Asinowski, Alon Regev

An ear in a triangulation $T$ of a convex $n$ -gon $P$ is a triangle of $T$ that shares two sides with $P$ itself. Certain enumerational and structural problems become easier when o…
