چکیده
It is proved that, for a prime number p, showing that an n-element matroid is not representable over GF (p) requires only O(n) rank evaluations.

An excluded minors method for infinite matroids
The notion of thin sums matroids was invented to extend the notion of representability to non-finitary matroids. A matroid is tame if every circuit-cocircuit intersection is finite. We prove that a tame matroid is a thin sums matroid over a finite field k if and only if all its finite minors are representable over k. We expect that the method we use to prove this will make it possible to lift m...
متن کاملk-Regular Matroids
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. This thesis considers the class of k–regular matroids, a generalization of the last two classes. Indeed, the classes of regular and near-regular matroids coincide wi...
متن کاملMatroids Representable Over Fields With a Common Subfield
A matroid is GF(q)-regular if it is representable over all proper superfields of the field GF(q). We show that, for highly connected matroids having a large projective geometry over GF(q) as a minor, the property of GF(q)-regularity is equivalent to representability over both GF(q) and GF(q) for some odd integer t ≥ 3. We do this by means of an exact structural description of
متن کاملOn the Representability of the Biuniform Matroid
Every bi-uniform matroid is representable over all sufficiently large fields. But it is not known exactly over which finite fields they are representable, and the existence of efficient methods to find a representation for every given bi-uniform matroid is an open problem too. The interest of these problems is due to their implications to secret sharing. Efficient methods to find representation...
متن کاملThin sums matroids and duality
Thin sums matroids were introduced to extend the notion of representability to non-finitary matroids. We give a new criterion for testing when the thin sums construction gives a matroid. We show that thin sums matroids over thin families are precisely the duals of representable matroids (those arising from vector spaces). We also show that the class of tame thin sums matroids is closed under du...
