Dual Grothendieck polynomials via last-passage percolation

24 Feb 2020 Yeliussizov Damir

The ring of symmetric functions has a basis of dual Grothendieck polynomials that are inhomogeneous $K$-theoretic deformations of Schur polynomials. We prove that dual Grothendieck polynomials determine column distributions for a directed last-passage percolation model...
