Hook Lengths in a Skew Young Diagram
نویسنده
چکیده
Regev and Vershik (Electronic J. Combinatorics 4 (1997), #R22) have obtained some properties of the set of hook lengths for certain skew Young diagrams, using asymptotic calculations of character degrees. They also conjectured a stronger form of one of their results. We give a simple inductive proof of this conjecture. Very recently, Regev and Zeilberger (Annals of Combinatorics, to appear) have independently proved this conjecture.

Hook Formulas for Skew Shapes
The celebrated hook-length formula gives a product formula for the number of standard Young tableaux of a straight shape. In 2014, Naruse announced a more general formula for the number of standard Young tableaux of skew shapes as a positive sum over excited diagrams of products of hook-lengths. We give an algebraic and a combinatorial proof of Naruse’s formula, by using factorial Schur functio...
متن کاملHook Formulas for Skew Shapes II. Combinatorial Proofs and Enumerative Applications
The Naruse hook-length formula is a recent general formula for the number of standard Young tableaux of skew shapes, given as a positive sum over excited diagrams of products of hook-lengths. In [MPP1] we gave two different q-analogues of Naruse’s formula: for the skew Schur functions, and for counting reverse plane partitions of skew shapes. In this paper we give an elementary proof of Naruse’...
متن کاملOn Principal Hook Length Partitions and Durfee Sizes in Skew Characters
We construct for a given arbitrary skew diagram A all partitions ν with maximal principal hook lengths among all partitions with [ν] appearing in [A]. Furthermore we show that these are also partitions with minimal Durfee size. We use this to give the maximal Durfee size for [ν] appearing in [A] for the cases when A decays into two partitions and for some special cases of A. We also deduce nece...

متن کاملComputing Multivariate Statistics
Many multivariate statistics are expressed as functions of the hypergeometric function of a matrix argument, or more generally, as series of Jack functions. This work is a collection of formulas, identities, and algorithms useful for the computations of these statistics in practice. Numerical examples are presented. 1. Definitions 1.1. Partitions and hook lengths. For an integer k ≥ 0 we say th...
