On existence of generalised Lehmer numbers modulo primes
Bikram Misra, Bidisha Roy, B. Sury
In this article, we discuss a multivariable analogue of Lehmer's parity problem. We generalise the notions of Lehmer numbers as Lehmer -tuples for a fixed odd prime . We coun…

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 and the additive convolution sum $\sum_{n < N} d(n) d…
