An explicit formula for Koornwinder moments and Rains' positivity conjecture

Younggwang Cho, Donghyun Kim, Jang Soo Kim +3

The asymmetric simple exclusion process (ASEP) is an important particle model with deep connections to orthogonal polynomials. Motivated by this connection, Corteel and Williams in…

Proof of a Conjecture on Young Tableaux with Walls

Zhicong Lin, Feihu Liu, Jiahang Liu +2

Banderier, Marchal, and Wallner considered Young tableaux with walls, which are similar to standard Young tableaux, except that local decreases are allowed at some walls. In this w…

A bijection between $321$ - and $213$ -avoiding permutations preserving $t$ -stack-sortability

Yang Li, Sergey Kitaev, Zhicong Lin +1

We construct a bijection between $321$ - and $213$ -avoiding permutations that preserves the property of $t$ -stack-sortability. Our bijection transforms natural statistics between th…
