Following Schubert varieties under Feigin's degeneration of the flag variety
Lara Bossinger, Martina Lanini
We describe the effect of Feigin's flat degeneration of the type flag variety on its Schubert varieties. In particular, we study when they stay irreducible and in seve…
Toric degenerations of Gr(2,n) and Gr(3,6) via plabic graphs
Lara Bossinger, Xin Fang, Ghislain Fourier +2
We establish an explicit bijection between the toric degenerations of the Grassmannian arising from maximal cones in tropical Grassmannians and the ones coming f…
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…
The degree of the Hilbert-Poincaré polynomial of PBW-graded modules
Teodor Backhaus, Lara Bossinger, Christian Desczyk +1
In this note, we study the Hilbert-Poincaré polynomials for the PBW-graded of simple modules for a simple complex Lie algebra. The computation of their degree can be reduced to mod…
