Let Tn denote the set of triangulations of a convex polygon K with n sides. We study functions that measure very natural “geometric” features of a triangulation τ ∈ Tn, for example ∆n(τ) which counts the maximal number of diagonals in τ incident to a single vertex of K. It is familiar that Tn is bijectively equivalent to Bn, the set of rooted binary trees with n− 2 internal nodes, and also to Pn, the set of non-negative lattice paths that start at 0, make 2n− 4 steps Xi of size ±1, and end at… CONTINUE READING
