Title:  Remarks on the differences between consecutive primes. (In English)
Source:  Elem. Math. 35, 115-118 (1980).
Review:  Define F(n,k), to be the number of solution of pj-pi = 2k, (pj \leq n), and let f(n,k) be the number for which j = i+1. This paper is concerned with the behaviour as n ––> oo of the maximum values of f(n,k) and F(n,k), and with the least values (kn and Kn respectively) for which the maxima are attained. Hardy and Littlewood gave a conjectured asymptotic formula for F(n,k), for fixed k. On the assumption of this it is shown that

f(n,kn)/{n(log n)-2 ––>}oo

and that kn ––> infty. In contrast it is shown that

F(n,Kn)/{n(log log n)(log n)-2 >> 1

without any hypothesis.
