The Generating Function of Ternary Trees and Continued Fractions
Ira Gessel, Guoce Xin
Michael Somos conjectured a relation between Hankel determinants whose entries count ternary trees and the number of certain plane partitions and alterna…
A Short Proof of the Zeilberger-Bressoud -Dyson Theorem
Ira M. Gessel, Guoce Xin
We give a formal Laurent series proof of Andrews's -Dyson Conjecture, first proved by Zeilberger and Bressoud.
A triple lacunary generating function for Hermite polynomials
Ira M. Gessel, Pallavi Jayawant
Some of the classical orthogonal polynomials such as Hermite, Laguerre, Charlier, etc. have been shown to be the generating polynomials for certain combinatorial objects. These com…
Signed Mahonians
Ron M. Adin, Ira M. Gessel, Yuval Roichman
A classical result of MacMahon gives a simple product formula for the generating function of major index over the symmetric group. A similar factorial-type product formula for the…
A Combinatorial Interpretation of The Numbers
Ira M. Gessel, Guoce Xin
It is well known that the numbers are integers, but in general there is no known combinatorial interpretation for them. When these numbers are the…
