What is … a Catalan Number?
This page hosts information on Jean-Philippe Labbé's talk "What is … a
Catalan Number?" at the
"What is …?" seminar. The talk will take place on Friday, October 22, 2:00pm at the BMS Loft at
Urania. Please note the special starting time.
Abstract
Catalan numbers form a sequence of natural numbers that counts a plethora of objects in mathematics. Thus, they appear constantly in enumerative combinatorics and many related fields like algebra, discrete geometry, representation theory and more. I will present their origin, discuss about some recursive and closed formulas and finally show some objects that are counted by Catalan numbers.
