Mathematics & Statistics Colloquium
Speaker: Dr. Joseph Kung, University of North Texas
Title: Moments of parking functions, Abel interpolation, and the number of trees and connected graphs
Date: September 6, 2013
Meet-and-Greet: 2:30 p.m. in Room 222 MM
Talk: 3:00 p.m. in Room 224 MM
Host: Dr. Xiangqian Zhou
ABSTRACT: We will explore the connection between factorial moments of parking functions and the number of labeled trees and connected graphs on n vertices and n+k edges. A tool in effecting this connection is Abel interpolation and Abel polynomials.
ABOUT THE SPEAKER: Dr. Kung is a professor of mathematics at University of North Texas. He attained his Ph.D at MIT in 1978 under his advisor, Dr. Gian-Carlo Rota His areas of research include combinatorics, matroid theory, lattice theory, classical invariant theory, arrangements of hyperplanes, etc. His research had been supported by NSF and NSA.
