G different from and has at least Δ edge-disjoint removable ears, where Δ is the maximum degree of G. This shows that any matching covered graph G has at least Δ! different ear decompositions, and thus is a generalization of the fundamental theorem of Lovász and Plummer establishing the existence of ear decompositions. We also show that every brick G different from and has Δ− 2 edges, each of which is a removable edge in G, that is, an edge whose deletion from G results in a matching covered…

Brick Generation and Conformal Subgraphs

- Mathematics
- 2016

This theorem is a refinement of the result of Carvalho, Lucchesi and Murty (2003) which is appropriate for the restricted class of near-bipartite bricks and establishes generation theorems which are specific to near-magnifying bricks.

On a Conjecture of Lovász Concerning Bricks: I. The Characteristic of a Matching Covered Graph

- MathematicsJ. Comb. Theory, Ser. B
- 2002

The notion of the characteristic of a separating cut in a matching covered graph is introduced and some basic properties are established to first prove the theorem for solid bricks, that is, bricks which do not have any nontrivial separating cuts.

Matching Covered Graphs with Three Removable Classes

This paper characterize matching covered graphs with precisely three removable classes and show, as a corollary, that every non-planar matching covered graph has at least four removable classes.

On perfect matchings in matching covered graphs

- MathematicsJ. Graph Theory
- 2019

There exist infinitely many $k-regular graphs of class 1 with an arbitrarily large equivalent class $K$ such that K is not switching-equivalent to either $\emptyset$ or $E(G)$, which provides a negative answer to the problem proposed by Lukot'ka and Rollova.

K4‐free and C6¯ ‐free Planar Matching Covered Graphs

- MathematicsJ. Graph Theory
- 2016

A solution to the problem of deciding which matching covered graphs are K4-based and which are -based is presented in the special case of planar graphs and the principal tool for proving the results is the brick generation procedure established by Norine and Thomas.

König Deletion Sets and Vertex Covers above the Matching Size

- MathematicsISAAC
- 2008

It is shown that the problem of deleting at most k vertices to make a given graph Konig-Egervary is fixed-parameter tractable with respect to k and an interesting parameter-preserving reduction from the vertex-deletion version of red/blue-split graphs to a version of Vertex Cover is shown.

The Complexity of König Subgraph Problems and Above-Guarantee Vertex Cover

- Mathematics, Computer ScienceAlgorithmica
- 2010

While studying the parameterized complexity of the problem of deleting k vertices to obtain a König-Egerváry graph, a number of interesting structural results on matchings and vertex covers are shown which could be useful in other contexts.

On the number of dissimilar pfaffian orientations of graphs

- MathematicsRAIRO Theor. Informatics Appl.
- 2005

It is deduced that the problem of determining whether or not a graph is Pfaffian is as difficult as the problemof determining whether a given orientation is PfAffian, a result first proved by Vazirani and Yanakakis.

Even cycles and perfect matchings in claw-free plane graphs

- MathematicsDiscret. Math. Theor. Comput. Sci.

It is shown that the only cycle-nice simple 3-connected claw-free plane graphs are $K_4$, $W_5$ and $\overline C_6$ and every cycle- Nice 2- connected claw- free plane graph can be obtained from a graph in the family ${\cal F}$ by a sequence of three types of operations.
