 GP_Seminar/2/">Jacobi–Trudi formulas for flagged refined dual stable Gro
 thendieck polynomials</a>\nby Jang Soo Kim (Sungkyunkwan University) as pa
 rt of IBS-CGP Seminar\n\n\nAbstract\nRecently Galashin\, Grinberg\, and Li
 u introduced the refined dual stable Grothendieck polynomials\, which are 
 symmetric functions in $x=(x_1\,x_2\,\\dots)$ with additional parameters $
 t=(t_1\,t_2\,\\dots)$. The refined dual stable Grothendieck polynomials ar
 e defined as a generating function for reverse plane partitions of a given
  shape. They interpolate between Schur functions and dual stable Grothendi
 eck polynomials introduced by Lam and Pylyavskyy in 2007. Flagged refined 
 dual stable Grothendieck polynomials are a more refined version of refined
  dual stable Grothendieck polynomials\, where lower and upper bounds are g
 iven for the entries of each row or column. In this talk we show Jacobi–
 Trudi-type formulas for flagged refined dual stable Grothendieck polynomia
 ls using plethystic substitution. This resolves a conjecture of Grinberg a
 nd generalizes a result by Iwao and Amanov–Yeliussizov.\n
