»Newton-Okounkov bodies for Grassmannians via mirror symmetry«

Abstract:
In recent work with L. Williams (arXiv:1712.00447) we use a X-cluster structure on the Grassmannian and the combinatorics of planar bicolored graphs to associate a Newton-Okounkov body to each X-cluster. We describe the Newton-Okounkov bodies explicitly using mirror symmetry: we show that they are polytopes whose facets can be read off from A-cluster expansions of the mirror Landau-Ginzburg model. We also give a combinatorial formula for the lattice points of the Newton-Okounkov bodies which has a surprising interpretation in terms of quantum Schubert calculus.

 

Hierzu ergeht herzliche Einladung.
