✦ Synopsis


Let 4 :=(* k ) k=0 be a sequence of distinct nonnegative real numbers with * 0 :=0 and k=1 1Â* k < . Let * # (0, 1) and = # (0, 1&*) be fixed. An earlier work of the authors shows that

is finite. In this paper an explicit upper bound for C(4, =, *) is given. In the special case * k :=k : , :>1, our bounds are essentially sharp. 1998 Academic Press . 1. INTRODUCTION In this paper 4 :=(* k ) k=0 always denotes a sequence of real numbers satisfying
