Bijecting hidden symmetries for skew staircase shapes

  title={Bijecting hidden symmetries for skew staircase shapes},
  author={Zachary Hamaker and Alejandro H. Morales and Igor Pak and Luis G. Serrano and Nathan Williams},
We present a bijection between the set SYT(λ/μ) of standard Young tableaux of staircase minus rectangle shape λ = δk, μ = (b a), and the set ShSYT′(η) of marked shifted standard Young tableaux of a certain shifted shape η = η(k, a, b). Numerically, this result is due to DeWitt (2012). Combined with other known bijections this gives a bijective proof of the product formula for |SYT(λ/μ)|. This resolves an open problem by Morales, Pak and Panova (2019), and allows an efficient random sampling…

Hook Formulas for Skew Shapes IV. Increasing Tableaux and Factorial Grothendieck Polynomials
We present a new family of hook-length formulas for the number of standard increasing tableaux which arise in the study of factorial Grothendieck polynomials. In the case of straight shapes our


A bijective proof of the hook-length formula for shifted standard tableaux
We present a bijective proof of the hook-length formula for shifted standard tableaux of a fixed shape based on a modified jeu de taquin and the ideas of the bijective proof of the hook-length

The major index generating function of standard Young tableaux of shapes of the form "staircase minus rectangle"
Abstract. A specialisation of a transformation formula for multi-dimensional elliptic hyper-geometric series is used to provide compact, non-determinantal formulae for the generatingfunction with

The combinatorics of standard setvalued Young tableaux with two-rows are explored, and how those tableaux may be used to provide new combinatorial interpretations of generalized Catalan numbers.
The Stembridge equality for skew stable Grothendieck polynomials and skew dual stable Grothendieck polynomials
The Schur polynomials s λ are essential in understanding the representation theory of the general linear group. They also describe the cohomology ring of the Grassmannians. For ρ = ( n,n − 1 ,..., 1)
