✦ Synopsis


For any integer r \ 1, let a(r) be the largest constant a \ 0 such that if E > 0 and 0 < c < c 0 for some small c 0 =c 0 (r, E) then every graph G of sufficiently large order n and at least

edges contains a copy of any (r+1)-chromatic graph H of independence number a(H) [ (a -E) log n log(1/c) .

Bateman and Erdo s found necessary and sufficient conditions on a set A for the kth differences of the partitions of n with parts in A, p (k) A (n), to eventually be positive; moreover, they showed that when these conditions occur p (k+1) A (n) tends to zero as n tends to infinity.

We show that every graph G of size at least 256 p 2 |G| contains a topological complete subgraph of order p. This slight improvement of a recent result of Komlós and Szemerédi proves a conjecture made by Mader and by Erdös and Hajnal.

Let A=[a 1 , a 2 , ...] N and put A(n)= a i n 1. We say that A is a P-set if no element a i divides the sum of two larger elements. It is proved that for every P-set A with pairwise co-prime elements the inequality A(n)<2n 2Â3 holds for infinitely many n # N. ## 2001 Academic Press where A(n)= a i
