A chain theorem for internally 4-connected binary matroids
نویسندگان
چکیده
Let M be a matroid. When M is 3-connected, Tutte’s WheelsandWhirls Theorem proves that M has a 3-connected proper minor N with exactly one element fewer than M unless M is a wheel or a whirl. I will present a corresponding result for internally 4-connected binary matroids. This presentation is based on joint work by myself, Dillon Mayhew, and James Oxley.

Towards a splitter theorem for internally 4-connected binary matroids II
Let M and N be internally 4-connected binary matroids such that M has a proper N -minor, and |E(N)| ≥ 7. As part of our project to develop a splitter theorem for internally 4-connected binary matroids, we prove the following result: if M\e has no N -minor whenever e is in a triangle of M , and M/e has no N -minor whenever e is in a triad of M , then M has a minor, M ′, such that M ′ is internal...

This paper proves a preliminary step towards a splitter theorem for internally 4-connected binary matroids. In particular, we show that, provided M or M∗ is not a cubic Möbius or planar ladder or a certain coextension thereof, an internally 4-connected binary matroid M with an internally 4-connected proper minor N either has a proper internally 4-connected minor M ′ with an N -minor such that |...
متن کاملA Splitter Theorem for Internally 4-Connected Binary Matroids
We prove that if N is an internally 4-connected minor of an internally 4-connected binary matroid M with E(N) ≥ 4, then there exist matroids M0,M1, . . . ,Mn such that M0 ∼= N , Mn = M , and, for each i ∈ {1, . . . , i}, Mi−1 is a minor of Mi, |E(Mi−1)| ≥ |E(Mi)| − 2, and Mi is 4-connected up to separators of size 5.
متن کاملTowards a Splitter Theorem for Internally 4-connected Binary Matroids Viii: Small Matroids
Our splitter theorem studies pairs of the form (M,N), where M and N are internally 4-connected binary matroids, M has a proper N -minor, and if M ′ is an internally 4-connected matroid such that M has a proper M ′-minor and M ′ has an N -minor, then |E(M)|− |E(M ′)| > 3. The analysis in the splitter theorem requires the constraint |E(M)| ≥ 16. In this article, we complement that analysis by des...

In our quest to find a splitter theorem for internally 4-connected binary matroids, we proved in the preceding paper in this series that, except when M or its dual is a cubic Möbius or planar ladder or a certain coextension thereof, an internally 4-connected binary matroid M with an internally 4connected proper minor N either has a proper internally 4-connected minor M ′ with an N -minor such t...
