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…
Combinatorics of orthogonal polynomials on the unit circle
Jihyeug Jang, Minho Song
Orthogonal polynomials on the unit circle (OPUC for short) are a family of polynomials whose orthogonality is given by integration over the unit circle in the complex plane. There…
Refined canonical stable Grothendieck polynomials and their duals, Part 2
Byung-Hak Hwang, Jihyeug Jang, Jang Soo Kim +2
This paper is the sequel of the paper under the same title with part 1, where we introduced refined canonical stable Grothendieck polynomials and their duals with two families of i…
Kemeny's constant and enumerating Braess edges in trees
Jihyeug Jang, Mark Kempton, Sooyeong Kim +3
We study the problem of enumerating Braess edges for Kemeny's constant in trees. We obtain bounds and asympotic results for the number of Braess edges in some families of trees.
Kemeny's constant and Wiener index on trees
Jihyeug Jang, Sooyeong Kim, Minho Song
On trees of fixed order, we show a direct relation between Kemeny's constant and Wiener index, and provide a new formula of Kemeny's constant from the relation with a combinatorial…
Negative moments of orthogonal polynomials
Jihyeug Jang, Donghyun Kim, Jang Soo Kim +2
If a sequence indexed by nonnegative integers satisfies a linear recurrence without constant terms, one can extend the indices of the sequence to negative integers using the recurr…
Refined canonical stable Grothendieck polynomials and their duals, Part 1
Byung-Hak Hwang, Jihyeug Jang, Jang Soo Kim +2
In this paper we introduce refined canonical stable Grothendieck polynomials and their duals with two infinite sequences of parameters. These polynomials unify several generalizati…
