String cone and Superpotential combinatorics for flag and Schubert varieties in type A
Lara Bossinger, Ghislain Fourier
We study the combinatorics of pseudoline arrangements and their relation to the geometry of flag and Schubert varieties. We associate to each pseudoline arrangement two polyhedral…
