چکیده

Let G be a graph. A G-trade of volume m is a pair (T ,T ′), where each of T and T ′ consists of m graphs, pairwise edge-disjoint, isomorphic to G, such that T ∩T ′ = ∅ and the union of the edge sets of the graphs in T is identical to the union of the edge sets of the graphs in T ′. Let X(G) be the set of non-negative integers m such that no G-trade of volume m exists. In this paper we prove that, for G ∈ G(n, 12 ), {1, 2, . . . , cn/ log n } ⊆ X(G) holds asymptotically almost surely, where c = log(4/3)/88.

Sufficient conditions for maximally edge-connected and super-edge-connected

Let $G$ be a connected graph with minimum degree $delta$ and edge-connectivity $lambda$. A graph ismaximally edge-connected if $lambda=delta$, and it is super-edge-connected if every minimum edge-cut istrivial; that is, if every minimum edge-cut consists of edges incident with a vertex of minimum degree.In this paper, we show that a connected graph or a connected triangle-free graph is maximall...

Packings in Complete Graphs

We deal with the concept of packings in graphs, which may be regarded as a generalization of the theory of graph design. In particular we construct a vertexand edge-disjoint packing of Kn (where n 2 mod 4 equals 0 or 1) with edges of different cyclic length. Moreover we consider edge-disjoint packings in complete graphs with uniform linear forests (and the resulting packings have special additi...

Dense packing on uniform lattices

We study the Hard Core Model on the graphs G obtained from Archimedean tilings i.e. configurations in {0,1} with the nearest neighbor 1’s forbidden. Our particular aim in choosing these graphs is to obtain insight to the geometry of the densest packings in a uniform discrete set-up. We establish density bounds, optimal configurations reaching them in all cases, and introduce a probabilistic cel...

Optimal Packings of Hamilton Cycles in Sparse Random Graphs

We prove that there exists a positive constant ε such that if log n/n ≤ p ≤ n−1+ε, then asymptotically almost surely the random graph G ∼ G(n, p) contains a collection of bδ(G)/2c edge-disjoint Hamilton cycles.
