Modules Pdf Module Mathematics Ring Mathematics The aim of this work is to show that (oriented) matroid methods can be applied to many discrete geometries, namely those based on modules over integral (ordered) domains. In section 6 we show that modules over integral domains have a natural matroidal structure, thereby showing that many discrete geometries can be treated within a frame work based on matroids.
Federico Ardila Matroid Theory Matroids are closely related with many other topics in discrete mathematics, such as graphs, matrices, codes and projective geometries. in this work, we define cyclic matroids as matroids over a ground set of size n whose automorphism group contains an n cycle. The authors provide a systematic development of the idempotent module theory of matroids, linking combinatorial, algebraic, and geometric aspects of these concepts. One can show that regular matroids are precisely those that are representable over r by a 1 totally unimodular matrix (ie, det b 2 f0; de nition of regular matroids. Throughout this paper, we observe how both graphs and matrices can be viewed as matroids. then we translate graph theory to linear algebra, and vice versa, using the language of matroids to facilitate our discussion.

Then, (e; i) is a matroid. proof : (i1) et (i2) are trivial. Matroids are combinatorial structures that capture the abstract properties of (linear algebraic ) dependence. see the article on matroids for theory and examples. But when we ask for the intersection of three matroids, the problem becomes np hard. Matroids were first described in 1935 by the mathematician hassler whitney as a combinatorial generalization of linear independence of vectors—“matroid” means “something sort of like a matrix”.
