Grothendieck polynomials of inverse fireworks permutations
Chen-An Chou, Tianyi Yu
Pipedreams are combinatorial objects that compute Grothendieck polynomials. We introduce a new combinatorial object that naturally recast the pipedream formula. From this, we obtai…

Constructing maximal pipedreams of double Grothendieck polynomials
Chen-An Chou, Tianyi Yu
Pechenik, Speyer and Weigandt defined a statistic on permutations which characterizes the leading monomial in top degree components of double Grothendieck…
