Minimum degree conditions for monochromatic cycle partitioning

نویسندگان

چکیده

A classical result of Erd?s, Gyárfás and Pyber states that any r-edge-coloured complete graph has a partition into O(r2log?r) monochromatic cycles. Here we determine the minimum degree threshold for this property. More precisely, show there exists constant c such on n vertices with at least n/2+c?rlog?n O(r2) We also provide constructions showing condition number cycles are essentially tight.

Minimum degree conditions for cycles

In this note we discuss the lengths of cycles which are forced to exist in an n-vertex graph with minimum degree δ. We show that for any integer k ≥ 2 there exists n0 such that if n ≥ n0 and G is an n-vertex graph with δ(G) = δ ≥ n/k then the following are true. (i) G contains Ct for every even 4 ≤ t ≤ ⌈ n k−1 ⌉ , (ii) either G is in a known exceptional class or G contains Ct for every odd t ∈ ...

Monochromatic cycle partitions of 2-coloured graphs with minimum degree 3n/4

Balogh, Barát, Gerbner, Gyárfás, and Sárközy proposed the following conjecture. Let G be a graph on n vertices with minimum degree at least 3n/4. Then for every 2-edge-colouring of G, the vertex set V (G) may be partitioned into two vertex-disjoint cycles, one of each colour. We prove that this conjecture holds for n large enough, improving approximate results by the aforementioned authors and ...

Minimum degree conditions for H-linked graphs

For a fixed multigraph H with vertices w1, . . . , wm, a graph G is H-linked if for every choice of vertices v1, . . . , vm in G, there exists a subdivision of H in G such that vi is the branch vertex representing wi (for all i). This generalizes the notions of k-linked, k-connected, and k-ordered graphs. Given a connected multigraph H with k edges and minimum degree at least two and n 7.5k, we...

The Order of Monochromatic Subgraphs with a Given Minimum Degree

Let G be a graph. For a given positive integer d, let fG(d) denote the largest integer t such that in every coloring of the edges of G with two colors there is a monochromatic subgraph with minimum degree at least d and order at least t. For n > k > d let f(n, k, d) denote the minimum of fG(d) where G ranges over all graphs with n vertices and minimum degree at least k. In this paper we establi...

Degree conditions and cycle extendability"

A non-Hamiltonian cycle C in a graph G is extendable if there is a cycle C' in G with V(C')= V(C) with one more vertex than C. For any integer k~>0, a cycle C is k-chord extendable if it is extendable to the cycle C' using at most k of the chords of the cycle C. It will be shown that if G is a graph of order n, then 6(G)>3n/4-1 implies that any proper cycle is 0-chord extendable, 6(G)>5n/9 impl...
