چکیده

A rainbow matching in an edge-colored graph is a matching in which all the edges have distinct colors. Wang asked if there is a function f(δ) such that a properly edgecolored graph G with minimum degree δ and order at least f(δ) must have a rainbow matching of size δ. We answer this question in the affirmative; an extremal approach yields that f(δ) = 98δ/23 < 4.27δ suffices. Furthermore, we give an O(δ(G)|V (G)|2)time algorithm that generates such a matching in a properly edge-colored graph of order at least 6.5δ.

Rainbow Matchings in Properly Edge Colored Graphs

Let G be a properly edge colored graph. A rainbow matching of G is a matching in which no two edges have the same color. Let δ denote the minimum degree of G. We show that if |V (G)| ≥ 8δ 5 , then G has a rainbow matching of size at least ⌊ 5 ⌋. We also prove that if G is a properly colored triangle-free graph, then G has a rainbow matching of size at least ⌊ 3 ⌋.

Rainbow matchings and partial transversals of Latin squares

In this paper we consider properly edge-colored graphs, i.e. two edges with the same color cannot share an endpoint, so each color class is a matching. A matching is called rainbow if its edges have different colors. The minimum degree of a graph is denoted by δ(G). We show that properly edge colored graphs G with |V (G)| ≥ 4δ(G) − 3 have rainbow matchings of size δ(G), this gives the best know...

Rainbow matchings and cycle-free partial transversals of Latin squares

In this paper we show that properly edge-colored graphs Gwith |V (G)| ≥ 4δ(G) − 3 have rainbow matchings of size δ(G); this gives the best known bound for a recent question of Wang. We also show that properly edge-colored graphs Gwith |V (G)| ≥ 2δ(G) have rainbow matchings of size at least δ(G) − 2δ(G)2/3. This result extends (with a weaker error term) the well-known result that a factorization...

Large Rainbow Matchings in Edge-Colored Graphs

A rainbow subgraph of an edge-colored graph is a subgraph whose edges have distinct colors. The color degree of a vertex v is the number of different colors on edges incident with v. Wang and Li conjectured that for k ≥ 4, every edge-colored graph with minimum color degree k contains a rainbow matching of size at least dk/2e. A properly edge-colored K4 has no such matching, which motivates the ...
