“…In fact, in general, the tropical prevariety of a collection of polynomials will properly contain the tropical prevariety of the ideal those polynomials generate. In the specific case of the complete flag variety, it is shown in [3,Example 5.2.4] that for n ≥ 6, F lDr n properly contains trF l n . Before getting to Theorem 4.11, we need to discuss one other type of Dressian.…”

“…We consider the set of points satisfying the tropicalizations of the incidence-Plücker relations, called the complete flag Dressian, F lDr n , and the set of points satisfying the tropicalizations of all polynomials in the incidence-Plücker ideal, called the tropical complete flag variety, T rF l n . These parameterize abstract flags of tropical linear spaces and realizable flags of tropical linear spaces, respectively [3].…”

“…In Sections 5 we discuss possible generalizations of our results in terms of a possible theory of buildings and complexes for tropical flag manifolds and flag varieties, which is inspired by some recent work in this field [BEZ21], [BH20]. We also recognize that the theory of finitely generated semimodules ties up with tropical convexity, as finitely generated semimodules are also considered as tropical cones in the literature [MS09], [Jos22].…”

“…Valuative functions of these polyhedra were studied in [6, 16] as invariants that behave well with respect to subdividing the associated combinatorial objects into smaller ones. In particular, matroid subdivisions have rich connection to geometry, such as compactifications of fine Schubert cells [25–27], tropical geometry [10, 36], and the K‐theory of Grassmannians [17, 37]. The valuativeness of many matroid invariants, such as the beta invariant and the Tutte polynomial, is a witness to such geometric connections.…”
