Rank-width of a graph G, denoted by rw(G), is a width parameter of graphs introduced by Oum and Seymour [J Combin Theory Ser B 96 (2006), 514-528]. We investigate the asymptotic behavior of rank-width of a random graph G(n, p). We show that, asymptotically almost surely, (i 2 ), then rw(G(n, p)) =

✦ Synopsis
We show that the number of points with pairwise different sets of neighbors in a graph is 0(2'/2), where T is the rank of the adjacency matrix. We also give an example that achieves this bound.

It was proved (A. Kotlov and L. Lovász, The rank and size of graphs, J. Graph Theory 23 (1996), 185-189) that the number of vertices in a twin-free graph is O(( √ 2) r ) where r is the rank of the adjacency matrix. This bound was shown to be tight. We show that the chromatic number of a graph is o(∆
We show that if the adjacency matrix of a graph X has 2-rank 2r, then the chromatic number of X is at most 2 r +1, and that this bound is tight. 2001
## Abstract Let __G__ be a graph and let __k__′(__G__) be the edge‐connectivity of __G__. The __strength__ of __G__, denoted by k̄′(__G__), is the maximum value of __k__′(__H__), where __H__ runs over all subgraphs of __G__. A simple graph __G__ is called k‐__maximal__ if k̄′(__G__) ≤ __k__ but for
## Abstract This article establishes a relationship between the real (circular) flow number of a graph and its cycle rank. We show that a connected graph with real flow number __p__/__q__ + 1, where __p__ and __q__ are two relatively prime numbers must have cycle rank at least __p__ + __q__ − 1. A
This paper shows that a simple graph which can be cellularly embedded on some closed surface in such a way that the size of each face does not exceed 7 is upper embeddable. This settles one of two conjectures posed by Nedela and S8 koviera (1990, in ``Topics in Combinatorics and Graph Theory,'' pp.
