چکیده
A graph is an apex if it contains a vertex whose deletion leaves planar graph. The family of graphs minor-closed and so characterized by finite list minor-minimal non-members. long-standing problem determining this obstructions remains open. This paper determines the 133 minor-minimal, non-apex that have connectivity two.

All Ramsey (2K2,C4)−Minimal Graphs
Let F, G and H be non-empty graphs. The notation F → (G,H) means that if any edge of F is colored by red or blue, then either the red subgraph of F con- tains a graph G or the blue subgraph of F contains a graph H. A graph F (without isolated vertices) is called a Ramsey (G,H)−minimal if F → (G,H) and for every e ∈ E(F), (F − e) 9 (G,H). The set of all Ramsey (G,H)−minimal graphs is denoted by ...
متن کاملExcluded-minor Characterization of Apex-outerplanar
The class of outerplanar graphs is minor-closed and can be characterized by two excluded minors: K4 and K2,3. The class of graphs that contain a vertex whose removal leaves an outerplanar graph is also minor-closed. We provide the complete list of 57 excluded minors for this class.
متن کاملList-coloring apex-minor-free graphs
A graph H is t-apex if H − X is planar for some set X ⊂ V (H) of size t. For any integer t ≥ 0 and a fixed t-apex graph H, we give a polynomial-time algorithm to decide whether a (t + 3)-connected Hminor-free graph is colorable from a given assignment of lists of size t+4. The connectivity requirement is the best possible in the sense that for every t ≥ 1, there exists a t-apex graph H such tha...

متن کاملAlmost All Friendly Matrices Have Many Obstructions
A symmetric m×m matrix M with entries taken from {0, 1, ∗} gives rise to a graph partition problem, asking whether a graph can be partitioned into m vertex sets matched to the rows (and corresponding columns) of M such that, if Mij = 1, then any two vertices between the corresponding vertex sets are joined by an edge, and if Mij = 0 then any two vertices between the corresponding vertex sets ar...
