Abstract: The paper provides a new combinatorial interpretation of the number of RNA secondary structures and some other Catalan-like numbers. On the basis of this interpretation a combinatorial proof of their logarithmic convexity is given.
Key words and phrases: log-convexity, Catalan-like numbers, RNA secondary structures.
