On some primary and secondary
structures in combinatorics
Department of Mathematics, Faculty of Science and Mathematics, University of Zagreb, Bijenička c. 30, HR-10002 Zagreb, Croatia
We will present some bijective proofs of some well known facts in combinatorics. Some refined structures, e.g. secondary structures will also be discussed. These include Catalan, Motzkin, Narayana and secondary structure numbers from biology. Some log-convexity properties and asymptotics of these numbers will also be presented.
