On the excluded minors for the matroids of branch-width \(k\)
In [\textit{N. Robertson} and \textit{P. D. Seymour}, J. Comb. Theory, Ser. B 52, 153-190 (1991; Zbl 0764.05069)], branch-width was introduced as a parameter for graphs and matroids. The present authors prove that the excluded minors for the class of matroids of branch-width \(k\) have size at most \((6^k-1)/5\).
