Title:Partition Polynomials: Asymptotics and Zeros
Seminar:Combinatorics/Partitions Seminar
Speaker:Dr. Robert Boyer, Drexel
Let F_n (x) be the partition polynomial \sum_{k=1}^n p_k (n) x^k where p_k (n) is the number of partitions of n with k parts. We emphasize the computational experiments using degrees up to 70, 000 to discover the asymptotics of these polynomials. Surprisingly, the asymptotics of F_n (x) have two scales of orders n and \sqrt{n} in three different regimes inside the unit disk. Consequently, the zeros converge to a network of curves inside the unit disk given in terms of the dilogarithm.
