Triple convolution sums of the generalised divisor functions and related sums over primes

Bikram Misra, Biswajyoti Saha

We study the triple convolution sum of the generalised divisor functions $n \leq x \sum d_{k} (n + h) d_{l} (n) d_{m} (n - h),$ where $h \leq x^{1 - ε}$ for any $ε > 0$ and $d_{k} (n)$ denotes the gen…

A triple convolution sum of the divisor function

Bikram Misra, M. Ram Murty, Biswajyoti Saha

We study the triple convolution sum of the divisor function given by $n \leq x \sum d (n) d (n - h) d (n + h)$ for $h \neq = 0$ and $d (n)$ denotes the number of positive divisors of $n$ . Ba…

On additive convolution sum of arithmetic functions and related questions

Bikram Misra, Biswajyoti Saha, Anubhav Sharma

Ingham studied two types of convolution sums of the divisor function, the shifted convolution sum $\sum_{n \leq N} d (n) d (n + h)$ and the additive convolution sum $\sum_{n < N} d(n) d…
