Seymour's conjecture on 2-connected graphs of large pathwidth
نویسندگان
چکیده
We prove the conjecture of Seymour (1993) that for every apex-forest H1 and outerplanar graph H2 there is an integer p such that every 2-connected graph of pathwidth at least p contains H1 or H2 as a minor. An independent proof was recently obtained by Dang and Thomas (arXiv:1712.04549).

Gallai's path decomposition conjecture for graphs of small maximum degree
Gallai’s path decomposition conjecture states that the edges of any connected graph on n vertices can be decomposed into at most n+1 2 paths. We confirm that conjecture for all graphs with maximum degree at most five.

One of the central problems in matroid theory is Rota's conjecture that, for all prime powers q, the class of GF(q)-representable matroids has a finite set of excluded minors. This conjecture has been settled for q s; 4 but remains open otherwise. Further progress towards this conjecture has been hindered by the fact that, for all q > 5, there are 3-connected GF(q)-representable matroids having...
متن کاملGallai's path decomposition conjecture for triangle-free planar graphs
A path decomposition of a graph G is a collection of edge-disjoint paths of G that covers the edge set of G. Gallai (1968) conjectured that every connected graph on n vertices admits a path decomposition of cardinality at most ⌊(n + 1)/2⌋. Gallai’s Conjecture has been verified for many classes of graphs. In particular, Lovász (1968) verified this conjecture for graphs with at most one vertex wi...
متن کاملA note on Fouquet-Vanherpe’s question and Fulkerson conjecture
The excessive index of a bridgeless cubic graph $G$ is the least integer $k$, such that $G$ can be covered by $k$ perfect matchings. An equivalent form of Fulkerson conjecture (due to Berge) is that every bridgeless cubic graph has excessive index at most five. Clearly, Petersen graph is a cyclically 4-edge-connected snark with excessive index at least 5, so Fouquet and Vanherpe as...
متن کاملMinors of two-connected graphs of large path-width
Let P be a graph with a vertex v such that P\v is a forest, and let Q be an outerplanar graph. We prove that there exists a number p = p(P,Q) such that every 2-connected graph of path-width at least p has a minor isomorphic to P or Q. This result answers a question of Seymour and implies a conjecture of Marshall and Wood.
