✦ Synopsis


Let Forb(G) denote the class of graphs with countable vertex sets which do not contain G as a subgraph. If G is finite, 2-connected, but not complete, then Forb(G) has no element which contains every other element of Forb(G) as a subgraph, i.e., this class contains no universal graph.

This conclusion is not universally accepted. Forsyth for example, argues that the writings of numerous Jesuit missionaries in Brazil in the sixteenth century makes a very strong case for cannibalism among the indigenous Tupi speaking Indians (Forsyth, 1983).

The linear arboricity la(G) of a graph G is the minimum number of linear forests that partition the edges of G. Akiyama, Exoo, and Harary conjectured for any simple graph G with maximum degree ∆. The conjecture has been proved to be true for graphs having ∆ =

Let G be a graph and let t Ն 0 be a real number. Then, We discuss how the toughness of (spanning) subgraphs of G and related graphs depends on (G), we give some sufficient degree conditions implying that (G) Ն t, and we study which subdivisions of 2-connected graphs have minimally 2-tough squares.

Colorings of disk graphs arise in the study of the frequency-assignment problem in broadcast networks. Motivated by the observations that the chromatic number of graphs modeling real networks hardly exceeds their clique number, we examine the related properties of the unit disk (UD) graphs and their

It is well known that a triplewhist tournament TWh(v) exists only if v ≡ 0 or 1 (mod 4) and v = 5, 9. In this article, we introduce a new concept TWh-frame and use it to show that the necessary condition for the existence of a TWh(v) is also sufficient with a handful possible exceptions of v ∈ {12,

Let N = N (q) be the number of nonzero digits in the binary expansion of the odd integer q. A construction method is presented which produces, among other results, a block circulant complex Hadamard matrix of order 2 α q, where α ≥ 2N -1. This improves a recent result of Craigen regarding the asympt
