On a conjecture of Erd?s, Graham and Spencer, II

It is conjectured by Erd?s, Graham and Spencer that if 1≤a₁≤a₂≤?≤a_s are integers with , then this sum can be decomposed into n parts so that all partial sums are ≤1. This is not true for as shown by a₁=?=a_n−2=1, . In 1997 Sandor proved that Erd?s-Graham-Spencer conjecture is true for . Recently, Chen proved that the conjecture is true for . In this paper, we prove that Erd?s-Graham-Spencer conjecture is true for .
