Let f be a positive multiplicative function and let k2 be an integer. We prove that if the prime values f(p) converge to 1 sufficiently slowly as p+, in the sense that p|f(p)1|=, there exists a real number c>0 such that the k-tuples (f(p+1),,f(p+k)) are dense in the hypercube [0,c]k or in [c,+)k. In particular, the values f(p+1),,f(p+k) can be put in any increasing order infinitely often. Our work generalises previous results of De Koninck and Luca.

移位素数上的乘法函数

f为正乘法函数,令ķ2是一个整数。我们证明如果质数F(p)足够缓慢地收敛到 1,因为p+, 在某种意义上说p|F(p)-1|=, 存在一个实数C>0使得k元组(F(p+1),,F(p+ķ)) 在超立方体中是稠密的 [0,C]ķ 或在 [C,+)ķ. 特别是,价值观F(p+1),,F(p+ķ)可以无限频繁地以任何递增的顺序排列。我们的工作概括了 De Koninck 和 Luca 以前的结果。
