On disjoint matchings in cubic graphs: Maximum 2-edge-colorable and maximum 3-edge-colorable subgraphs
We show that any 2−factor of a cubic graph can be extended to a maximum 3−edge-colorable subgraph. We also show that the sum of sizes of maximum 2− and 3−edge-colorable subgraphs of a cubic graph is at least twice of its number of vertices.
متن کاملMaximum Δ-edge-colorable subgraphs of class II graphs
A graph G is class II, if its chromatic index is at least ∆ + 1. Let H be a maximum ∆-edge-colorable subgraph of G. The paper proves best possible lower bounds for |E(H)| |E(G)| , and structural properties of maximum ∆-edge-colorable subgraphs. It is shown that every set of vertex-disjoint cycles of a class II graph with ∆ ≥ 3 can be extended to a maximum ∆-edge-colorable subgraph. Simple graph...
متن کاملApproximating the Maximum 3- and 4-Edge-Colorable Subgraph
We study large k-edge-colorable subgraphs of simple graphs and multigraphs. We show that: – every simple subcubic graph G has a 3-edge-colorable subgraph (3ECS) with at least 13 15 |E(G)| edges, unless G is isomorphic to K4 with one edge subdivided, – every subcubic multigraph G has a 3-ECS with at least 7 9 |E(G)| edges, unless G is isomorphic to K3 with one edge doubled, – every simple graph ...
متن کاملTriangle-free Uniquely 3-Edge Colorable Cubic Graphs
This paper presents infinitely many new examples of triangle-free uniquely 3-edge colorable cubic graphs. The only such graph previously known was given by Tutte in 1976.
متن کاملOn spanning $k$-edge-colorable subgraphs
A subgraph H of a multigraph G is called strongly spanning, if any vertex of G is not isolated in H , while it is called maximum k-edge-colorable, if H is proper k-edge-colorable and has the largest size. We introduce a graph-parameter sp(G), that coincides with the smallest k that a graph G has a strongly spanning maximum k-edge-colorable subgraph. Our first result offers some alternative defi...
