Action graphs, rooted planar forests, and self-convolutions of the Catalan numbers

Julia E. Bergner, Cedric Harper, Ryan Keller and Mathilde Rosi-Marshall

Vol. 14 (2021), No. 3, 387–399
Abstract

We show that families of action graphs, with initial graphs which are linear of varying length, give rise to self-convolutions of the Catalan sequence. We also give a comparison with planar rooted forests with a fixed number of trees.

Keywords
Catalan numbers, convolution of sequences, action graphs
