The structure of almost all graphs in a hereditary property

A hereditary property of graphs is a collection of graphs which is closed under taking induced subgraphs. The speed of P is the function n 7→ |Pn|, where Pn denotes the graphs of order n in P . It was shown by Alekseev, and by Bollobás and Thomason, that if P is a hereditary property of graphs then |Pn| = 2 2/2, where r = r(P) ∈ N is the so-called ‘colouring number’ of P . However, their result...

Almost all H-free graphs have the Erdős-Hajnal property

Erdős and Hajnal conjectured that, for every graph H, there exists a constant (H) > 0 such that every H-free graph G (that is, not containing H as an induced subgraph) must contain a clique or an independent set of size at least |G| . We prove that there exists (H) such that almost every H-free graph G has this property, meaning that, amongst the H-free graphs with n vertices, the proportion ha...

On an adjacency property of almost all graphs

A graph is called n-existentially closed or n-e.c. if it satis/es the following adjacency property: for every n-element subset S of the vertices, and for every subset T of S, there is a vertex not in S which is joined to all of T and to none of S\T . The unique countable random graph is known to be n-e.c. for all n. Equivalently, for any /xed n, almost all /nite graphs are n-e.c. However, few e...

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
