graph maximum genusalgorithmEar decomposition of a graph has been extensively studied in relation to graph connectivity. In this paper, a connection of ear decomposition to graph embeddings is exhibited. It is shown that constructing a maximum-paired ear decomposition of a graph and constructing a ...

1) ear decomposition 耳朵分解 1. It is shown that let G be a bipartite graph withbipartition (X,Y) and with a perfect matching M , then G is 1_extendable if and only if G has anear decomposition G=e+P 1+P 2+. 文章证明:G是1_可扩图当且仅当G有如下耳朵分解G=e+P1+P2+…+Pr使...
Lovász shows that a matching covered graph G has an ear decomposition starting with an arbitrary edge of G. A 2-edge-connected cubic graph is matching covered. Using Oum’s characterization of 2-edge-connected claw-free cubic graphs (Oum, 2011) , this paper gives a characterization of 2-...

A graph is called #phi#-convered if each edge may lie onan even ear of an optimal ear-decomposition. Several theorems on matching-covered graphs will be generalized for #phi#-covered graphs.Z.SzigetiInteger programming and combinatorial optimization: 7th international conference on integer ...
We show that when building an ear decomposition of a cubic bridgeless graph, it is possible to do this so that at each step, the graph outside the already built two-connected subgraph, has a 2-factor. It shall also be shown that every edge in a cubic bipartite graph is either a ...
