Fix $r\geq 4$. Let $U(r,n)$ be the uniform matroid of rank $r$ on an $n$-element ground set, and let $\mathscr{D}(U(r,n))$ be its Dressian. For a valuation…

Let $\operatorname{TGr}_0(k,n)$ denote the characteristic-zero tropical Grassmannian, let $\operatorname{Dr}(k,n)$ denote the Dressian, and let $\mathcal I_{n,k}$ be the Plücker id…
