M = the positive tropical grassmannian, the hypersimplex, and the 2 amplituhedron

HIGHLIGHTS

• who: Tomasz u0141ukowski and collaborators from the Department of Physics, Astronomy and Mathematics, University of, USA have published the paper: m = The Positive Tropical Grassmannian, the Hypersimplex, and the 2 Amplituhedron, in the Journal: (JOURNAL) of November/12,/2021
• what: What the authors show in this paper is that the appearance of the number n-2 in k the context of both the hypersimplex k+1,n and the amplituhedron An,k (Z) is not a coincidence! The authors show in Section 7 that the rather mysterious parity duality, which relates dissections of An,k . . .
