1. The function h (b_1,..., bk). Let A_k={a1,...,ak}N with gcd (a1,...,ak)=1. In order to determine g(Ak)=g(a1,...,ak), defined as the greatest n with no representation. we introduce two functions h (Bk) and d(Bk) and study the connections to g (Ak). If we use partial summation in (1) we obtain. we then have, equivalently to (1), a representation.
