Growth rates of minor-closed classes of matroids
نویسندگان
چکیده
For a minor-closed class M of matroids, we let h(k) denote the maximum number of elements of a simple rank-k matroid in M. We prove that, if M does not contain all simple rank-2 matroids, then h(k) grows either linearly, quadratically, or exponentially.

Exponentially Dense Matroids
This thesis deals with questions relating to the maximum density of rank-n matroids in a minor-closed class. Consider a minor-closed class M of matroids that does not contain a given rank-2 uniform matroid. The growth rate function is defined by hM(n) = max (|M | : M ∈M simple, r(M) ≤ n) . The Growth Rate Theorem, due to Geelen, Kabell, Kung, and Whittle, shows that the growth rate function is ...
متن کاملSome Open Problems on excluding a Uniform Matroid
It would appear that minor-closed classes of matroids that are representable over any given finite field are very well behaved. This paper explores what happens when we go a little further to minor-closed classes of matroids that exclude a uniform minor. Numerous open problems of varying difficulty are posed.
متن کاملThe Highly Connected Matroids in Minor-closed Classes
For any minor-closed class of matroids over a fixed finite field, we state an exact structural characterization for the sufficiently connected matroids in the class. We also state a number of conjectures that might be approachable using the structural characterization. This paper is dedicated to James Oxley on the occasion of his 60th Birthday.
متن کاملStructure in minor-closed classes of matroids
This paper gives an informal introduction to structure theory for minorclosed classes of matroids representable over a fixed finite field. The early sections describe some historical results that give evidence that well-defined structure exists for members of such classes. In later sections we describe the fundamental classes and other features that necessarily appear in structure theory for mi...
متن کاملGrowth rate functions of dense classes of representable matroids
For each proper minor-closed subclassM of the GF(q)representable matroids containing all GF(q)-representable matroids, we give, for all large r, a tight upper bound on the number of points in a rank-r matroid inM, and give a rank-r matroid inM for which equality holds. As a consequence, we give a tight upper bound on the number of points in a GF(q)-representable, rank-r matroid of large rank wi...
