Abstract
Let N be a minor of a 3-connected matroid M and let M′ be a 3-connected minor of M that is minimal having N as a minor. This paper commences the study of the problem of finding a best-possible upper bound on |E(M′) - E(N)|. The main result solves this problem in the case that N and M have the same rank. © 2000 Elsevier Science B.V. All rights reserved.
