 nar/2/">Jacobi–Trudi formulas for flagged refined dual stable Grothendie
 ck polynomials</a>\nby Jang Soo Kim (Sungkyunkwan University) as part of I
 BS-CGP Seminar\n\n\nAbstract\nRecently Galashin\, Grinberg\, and Liu intro
 duced the refined dual stable Grothendieck polynomials\, which are symmetr
 ic functions in $x=(x_1\,x_2\,\\dots)$ with additional parameters $t=(t_1\
 ,t_2\,\\dots)$. The refined dual stable Grothendieck polynomials are defin
 ed as a generating function for reverse plane partitions of a given shape.
  They interpolate between Schur functions and dual stable Grothendieck pol
 ynomials introduced by Lam and Pylyavskyy in 2007. Flagged refined dual st
 able Grothendieck polynomials are a more refined version of refined dual s
 table Grothendieck polynomials\, where lower and upper bounds are given fo
 r the entries of each row or column. In this talk we show Jacobi–Trudi-t
 ype formulas for flagged refined dual stable Grothendieck polynomials usin
 g plethystic substitution. This resolves a conjecture of Grinberg and gene
 ralizes a result by Iwao and Amanov–Yeliussizov.\n
