Title:Longest Run of Equal Parts in a Random Integer Composition
Seminar:Combinatorics/Partitions Seminar
Speaker:Ayla Gafni, PSU
This talk examines a problem in enumerative and asymptotic combinatorics involving the classical structure of integer compositions. What is sought is an analysis on average and in distribution of the length of the longest run of consecutive equal parts in a composition of size n. I will discuss symbolic methods for constructing useful generating functions as well as how singularity analysis can be used to determine asymptotic behavior. The problem was posed by Herbert Wilf at the 2009 Analysis of Algorithms conference, and I solved it during a Summer 2009 internship at INRIA-Rocquencourt under the direction of Philippe Flajolet.
