چکیده
For a graph G, let σ2(G) = min{d(u) + d(v) : uv / ∈ E(G)}. We prove that every n-vertex graph G with σ2(G) ≥ 4n/3−1 contains each 2-regular n-vertex graph. This extends a theorem due to Aigner and Brandt and to Alon and Fisher.

On a family of cubic graphs containing the flower snarks
We consider cubic graphs formed with k ≥ 2 disjoint claws Ci ∼ K1,3 (0 ≤ i ≤ k−1) such that for every integer i modulo k the three vertices of degree 1 of Ci are joined to the three vertices of degree 1 of Ci−1 and joined to the three vertices of degree 1 of Ci+1. Denote by ti the vertex of degree 3 of Ci and by T the set {t1, t2, ..., tk−1}. In such a way we construct three distinct graphs, na...
متن کاملA Short Proof of a Theorem of Kano and Yu on Factors in Regular Graphs
In this note we present a short proof of the following result, which is a slight extension of a nice 2005 theorem by Kano and Yu. Let e be an edge of an rregular graph G. If G has a 1-factor containing e and a 1-factor avoiding e, then G has a k-factor containing e and a k-factor avoiding e for every k ∈ {1, 2, . . . , r−1}.
متن کاملLong cycles in graphs containing a 2-factor with many odd components
We prove a result on the length of a longest cycle in a graph on n vertices that contains a 2-factor and satisfies d(u)+ d(v)+d(w)~> n + 2 for every triple u, v, w of independent vertices. As a corollary we obtain the following improvement of a conjecture of H/iggkvist (1992): Let G be a 2-connected graph on n vertices where every pair of nonadjacent vertices has degree sum at least n-k and ass...
متن کاملGraphs containing triangles are not 3-common
Jagger, S̆t̆ov́ıc̆ek and Thomason [3] defined the class of k-common graphs, and showed among other results that every graph containing K4 as a subgraph is not 2-common. We prove that every graph containing K3 as a subgraph is not 3-common.
متن کاملGraphs with 1-factors
In this paper it is shown that if G is a connected graph of order 2n (n> 1) not containing a 1-factor, then for each k, Kk^n, there exists an induced, connected subgraph of order 2k which also fails to possess a 1-factor. Several other sufficient conditions for a graph to contain a 1-factor are presented. In particular, it is seen that the connected even order line graphs and total graphs alway...
