Abstract:
The Hodge algebra structures on the homogeneous coordinate rings of Grassmann
varieties provide semi-toric degenerations of these varieties. In this paper we
construct these semi-toric degenerations using quasi-valuations and
triangulations of Newton–Okounkov bodies.
Key words and phrases:
distributive lattice, Hibi variety, standard monomial theory, toric
degeneration, Newton–Okounkov body, Grassmann variety.
