From standard monomial theory to semi-toric degenerations via Newton-Okounkov bodies

Published 27 Sep 2017 in math.AG, math.CO, and math.RA | (1709.09734v1)

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.
