Deutsch paths and their enumeration

Combinatorics 2020-04-16 v2

Abstract

A variation of Dyck paths allows for down-steps of arbitrary length, not just one. Credits for this invention are given to Emeric Deutsch. Surprisingly, the enumeration of them is somewhat akin to the analysis of Motzkin-paths; the last section contains a bijection.

Comments

The last section (new) contains a bijection between open Deutsch paths and Motzkin paths, of the same length
