Abstract:Suppose that k and l are integers such that 
$$k \geqslant 2$$
and 
$$l \geqslant 2$$
, M k is a set of numbers without kth powers, and 
$$\tau \left( n \right) = \sum {_{d\left| n \right.} } 1$$
. In this paper, we obtain asymptotic estimates of the sums 
$$\sum {\tau \left( n \right)\tau \left( {n + 1} \right)}$$
over 
$$n \leqslant x,n \in M_k$$
Keywords:Ingham divisor problem  multiplicative arithmetical function  asymptotic relation
