On some primary and secondary structures in combinatorics
D. Veljan
Abstract
A possible upgrade of a curriculum in undergraduate
course in combinatorics is presented by giving more bijective
proofs in the standard (or primary) combinatorics and by adding
some topics on more refined (or secondary) combinatorics,
including Dyck and Motzkin paths, Catalan, Narayana and Motzkin
numbers and secondary structures coming from biology. Some
log-convexity properties and asymptotics of these numbers are
also presented.
Keywords
Catalan numbers; Narayana numbers; Motzkin numbers; secondary structure; log-convexity
