# On the maximal number of independent circuits in a graph

@article{Dirac1963OnTM, title={On the maximal number of independent circuits in a graph}, author={G. A. Dirac and Paul L. Erdos}, journal={Acta Mathematica Academiae Scientiarum Hungarica}, year={1963}, volume={14}, pages={79-94} }

In a recent paper [l] K . CORRÁDI and A. HAJNAL proved that if a finite graph without multiple edges contains at least 3k vertices and the valency of every vertex is at least 2k, where k is a positive integer, then the graph contains k independent circuits, i . e . the graph contains as a subgraph a set of k circuits no two of which have a vertex in common . The present paper contains extensions of this theorem. In a recent paper [2] P . ERDŐS and L. PÓSA proved, among other things, that if a…

SUFFICIENT CONDITION FOR THE EXISTENCE OF THREE DISJOINT THETA GRAPHS

- Mathematics
- 2015

A theta graph is the union of three internally disjoint paths that have the same two distinct end vertices. We show that every graph of order n ≥ 12 and size at least ⌊ 11n−18 2 ⌋ contains three…

Extremal problems on planar graphs without k edge-disjoint cycles

- Mathematics

In the 1960s, Erd ˝ os and his cooperators initiated the research of the maximum numbers of edges in a graph or a planar graph on n vertices without k edge-disjoint cycles. This problem had been…

Minimum Degree Conditions for Tilings in Graphs and Hypergraphs

- Mathematics
- 2011

We consider tiling problems for graphs and hypergraphs. For two graphs G and F , an F -tiling of F is a subgraph of G consisting of only vertex disjoint copies of F . By using the absorbing method we…

Packing a forest with a graph

The case that one of G and H is a forest, i.e., a graph with no cycles is considered, and kG is defined to be the vertex-disjoint union of k copies of G for any positive integer k and graph G.

K − `-factors in graphs

- Mathematics
- 2005

Given two graphs H and G, an H-packing in G is a collection of vertex-disjoint copies of H in G. An H-packing in G is called perfect if it covers all vertices of G. In this case, we also say that G…

Triangle factors of graphs without large independent sets and of weighted graphs

- MathematicsRandom Struct. Algorithms
- 2016

The minimum degree condition necessary to guarantee a triangle factor in graphs with sublinear independence number is determined, and it is shown that if G is an n-vertex graph with (G) = o(n) and ( G) (1=2 + o(1))n, then G has a Triangle factor and this is asymptotically best possible.

A refinement of a result of Corrádi and Hajnal

It is proved that for s∈{3,4} if an sk-vertex graph G with maximum degree at most k has no equitable k-coloring, then G either contains Kk+1 or k is odd and G containing Kk,k.

Towards a Weighted Version of the Hajnal–Szemerédi Theorem

- MathematicsCombinatorics, Probability and Computing
- 2013

This paper proposes investigating the relation between minimum degree and existence of perfect Kr-packing for edge-weighted graphs and provides some lower and upper bounds and a conjecture on the asymptotics of the threshold as n goes to infinity.
