MIN-turns and MAX-turns in k-Dyck paths: a pure generating function approach

Combinatorics 2023-09-04 v3

Abstract

kk-Dyck paths differ from ordinary Dyck paths by using an up-step of length kk. We analyze at which level the path is after the ss-th up-step and before the (s+1)(s+1)st up-step. In honour of Rainer Kemp who studied a related concept 40 years ago the terms \textsc{max}-terms and \textsc{min}-terms are used. Results are obtained by an appropriate use of trivariate generating functions; practically no combinatorial arguments are used.
