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
