Abstract

Let F be a collection of 3-connected matroids which is (3, 1)-rounded, that is, whenever a 3-connected matroid M has a minor in F and e is an element of M, then M has a minor in F whose ground set contains. e. The aim of this note is to prove that, for all sufficiently large n, the collection of n-element 3-connected matroids having some minor in F is also (3, 1)-rounded. © 1989 Akadémiai Kiadó.
