Wall-Crossing for Newton–Okounkov Bodies and the Tropical Grassmannian

Wall-Crossing for Newton–Okounkov Bodies and the Tropical Grassmannian

Tropical geometry and the theory of Newton-Okounkov bodies are two methods which produce toric degenerations of an irreducible complex projective variety. Kaveh-Manon showed that the two are related. We give geometric maps between the Newton-Okounkov bodies corresponding to two adjacent maximal-dimensional prime cones in the tropicalization of $X$. Under a …
