WebNov 1, 2024 · The tropical Grassmannian, denoted trop (Gr (k, C n)) ⊂ R (n k) is the tropical variety of the Plücker ideal I k, n. By [21, Corollary 3.1] it is a k (n − k) + 1-dimensional polyhedral fan whose maximal cones are all of this dimension. We mainly focus on the tropicalization of Gr (2, C n).
