AbstractThree types of matroid connectivity, including Tutte's, are defined and shown to generalize corresponding notions of graph connectivity. A theorem of Tutte on cyclically 3-connected graphs, is generalized to matroids.

Boundaries of Coxeter Matroids
The purpose of this paper is to introduce, for a finite Coxeter groupW, the mod2 boundary operator on the space of all Coxeter matroids (also known asWP-matroids) forWandP, wherePvaries through all the proper standard parabolic subgroups ofW(Theorem 3 of

Oriented-valuated matroids and real tropical linear spaces
We intend to give a correspondence between matroids over the hyperfield $\Ss\T$ with real tropical linear spaces. The first of these objects are generalizations of matroids using hyperfield theory, which have forgetful functors that give valuated ...

The class of matroids representable over all fields is the class of regular matroids. The class of matroids representable over all fields except perhaps GF(2) is the class of near-regular matroids. Let k be a non-negative integer.

Topics representability of matroids over finite and infinite fields
En este trabajo presentamos un estudio de algunos de los aspectos más importantes de la teoría de matroides sobre campos finitos e infinitos, así como también exponemos las caracterizaciones de la clase de matroides F-representables vía menores excluídos.
