Oriented matroid

Oriented matroid of a point con guration: The oriented matroid of the associated vector con guration. Covector of a vector con guration X: Partition of X = (x1;:::;xn) induced by a linear hyperplane, into points on the hyperplane, on the positive side, and on the negative side. Oriented matroid of X: The collection L f ;0;+gn of all covectors of X An oriented matroid is a pair , where E is a finite set, and is a set of covectors in . The big face lattice of an oriented matroid is the poset , where `` '' denotes the inclusion of supports

Oriented matroid's wiki: An oriented matroid is a mathematical structure that abstracts the properties of directed graphs and of arrangements of vectors in a vector. If the feasible region is nonempty and bounded in the direction of the gradient of the objective function, then there will always be a solution to the LP problem LECTURES ON MATROIDS AND ORIENTED MATROIDS VICTOR REINER Abstract. These lecture notes were prepared for the Algebraic Combina-torics in Europe (ACE) Summer School in. This chapter reviews oriented matroids. Matroid theory can be considered as coordinate-free linear algebra, and it has been applied to various fields in mathematics Welcome to the Homepage of Oriented Matroids. This site is dedicated to objects in discrete geometry and their abstraction in terms of oriented matroids

Abstract: In his seminal 1983 paper, Jim Lawrence introduced lopsided sets and featured them as asymmetric counterparts of oriented matroids, both sharing the key. Matroid theory borrows extensively from the terminology of linear algebra and graph theory, largely because it is the abstraction of various notions of central importance in these fields. Matroids have found applications in geometry, topology, combinatorial optimization, network theory and coding theory Kindle-Shop.

Oriented-matroid theory allows a combinatorial approach to the max-flow min-cut theorem. A network with the value of flow equal to the capacity of an s-t cu to realizability is a fruitful source for producing examples and counterexamples in many di erent mathematical disciplines. Here we present two such oriented matroids
