Representations of Matroids in Semimodular Lattices
We prove equivalence of two definitions of representability of matroids: representation by vector configurations and representation by retraction of buildings of type An. Proofs are given in a more general context of representation of matroids in semimodular lattices and Coxeter matroids in chamber systems with group metric.
متن کاملOn Exchange Axioms for Valuated Matroids and Valuated Delta-Matroids
Two further equivalent axioms are given for valuations of a matroid. Let M = (V,B) be a matroid on a finite set V with the family of bases B. For ω : B → R the following three conditions are equivalent: (V1) ∀B,B′ ∈ B, ∀u ∈ B −B′,∃v ∈ B′ −B: ω(B) + ω(B′) ≤ ω(B − u+ v) + ω(B′ + u− v); (V2) ∀B,B′ ∈ B with B 6= B′, ∃u ∈ B −B′,∃v ∈ B′ −B: ω(B) + ω(B′) ≤ ω(B − u+ v) + ω(B′ + u− v); (V3) ∀B,B′ ∈ B, ∀...
متن کاملTwo Algorithms for Valuated ∆-matroids
Two algorithms are proposed for computing the maximum degree of a principal minor of specified order of a skew-symmetric rational function matrix. The algorithms are developed in the framework of valuated ∆matroid of Dress and Wenzel, and are valid also for valuated ∆-matroids in general.
متن کاملSemimodular Lattices and Semibuildings
In a ranked lattice, we consider two maximal chains, or “flags” to be i-adjacent if they are equal except possibly on rank i . Thus, a finite rank lattice is a chamber system. If the lattice is semimodular, as noted in [9], there is a “Jordan-Hölder permutation” between any two flags. This permutation has the properties of an Sn-distance function on the chamber system of flags. Using these noti...
متن کاملIsotropical linear spaces and valuated Delta-matroids
The spinor variety is cut out by the quadratic Wick relations among the principal Pfaffians of an n×n skewsymmetric matrix. Its points correspond to n-dimensional isotropic subspaces of a 2n-dimensional vector space. In this paper we tropicalize this picture, and we develop a combinatorial theory of tropical Wick vectors and tropical linear spaces that are tropically isotropic. We characterize ...
