What is the "archetypal" photograph that involves brain while one thinks of an enormous graph? What with a finite graph - whilst it truly is considered against an unlimited one? What structural components are ordinary for both - through their presence or absence - but supply a typical floor for either? In making plans the workshop on "Cycles and Rays" it were meant from the outset to deliver countless graphs to the fore up to attainable. There by no means were a graph theoretical assembly within which limitless graphs have been greater than "also rans", not to mention one within which they have been a relevant subject. partly, it is a subject of favor, inasmuch as they're perceived as now not easily lending themselves to purposes, partly it's a subject of psychology stemming from the lack of confidence that many graph theorists believe within the face of set thought - on which limitless graph conception is predicated to a substantial volume. the result's that customarily, limitless graph theorists understand what's taking place in finite graphs yet now not conversely. lack of know-how approximately endless graph idea can be present in authoritative l resources. for instance, a up to date variation (1987) of a massive mathematical encyclopaedia proposes to ". . . limit [itself] to finite graphs, when you consider that basically they offer a standard theory". If whatever, the opposite is right, and take into account that, the graph theoretical global is aware higher. One might ask yourself, notwithstanding, through how much.

Decompositions into cycles and edges were considered by Erdos and Gallai (see [9]). Conjecture CED (P. Erdos and T. Gallai) Every simple graph on n vertices admits a decomposition into at most cn cycles and edges, where c is an absolute constant. Dean [7] discusses versions of Conjecture SCD for eulerian digraphs of various types. 2 A path cover (PC) of a graph G is a collection P of paths of G such that each edge of G belongs to at least one path of P. A cycle cover (CC) of a graph G is a collection C of cycles of G such that each edge of G belongs to at least one cycle of C.
4 A small cycle decomposition (SCD) of a graph G is a CD C of G such that ICI ::; (n - 1)/2, where n = IV(G)I. Conjecture SCD (G. Haj6s) Every simple even groph admits an SCD. 3 The statement in [28) of Conjecture SCD is marginally weaker than the one given here, the bound on ICI being n/2 instead of (n-l)/2. However, Dean [7] has observed that the two are, in fact, equivalent. 1. 5 A small cycle double cover (SCnC) of a graph G on n vertices is a cnc n - 1. Cof G such that IC I ~ Conjecture SCDC (The Small Cycle Double Cover Conjecture) Every simple 2-edge-connected graph admits an SCDC.
Thus IGI < m. Since x, y E m are --(-incomparable iff either x < y and y ex, or y < x and x C y, every anti chain A of (m, --() is a well ordered subset of (m, $-I)j especially IAI < m. Thus we have non P( m). (1 => 3) follows immediately from the definition of weak compactness. 0 Corollary 2 P = Q. Corollary 3 P( m) if and only if m E {O, 1,2, wo} or m is weakly compact. A. Jung.
