On $B^{4}$ -almost periodicity for a class of arithmetical functions

Kritika Aggarwal, Debika Banerjee, Shubham Gupta

In this paper, we establish the $B^{4}$ -almost periodicity in the sense of Besicovitch for a suitably normalized error term associated with a broad class of arithmetical fu…

A weighted divisor problem and exponential sum

Kritika Aggarwal, Debika Banerjee

In this paper, we investigate a weighted divisor problem involving the exponential sum of $D_{(1)} (n)$ , the $n$ th coefficient in the Dirichlet series expansion of $ζ^{'} (s)^{2}$ . We est…
