Mobius disjointness conjecture on the product of a circle and the Heisenberg nilmanifold
Jing Ma, Ronghui Wu
Let be the unit circle and the 3-dimensional Heisenberg nilmanifold. We prove that the Möbius function is linearly disjoint from a class of distal skew…
On a sum involving general arithmetic functions and the integral part function
Jing Ma, Ronghui Wu
Let be an arithmetic function satisfying some simple conditions. The aim of this paper is to establish an asymptotical formula for the quantity \[ S_f(x):=\sum_{n\leq x}\frac{f…
On a sum involving certain arithmetic functions and the integral part function
Jing Ma, Huayan Sun
In this short, we study sums of the shape where is Euler totient function , Dedekind function , sum-of-divisors function or t…
The Average Size of Ramanujan Sums over Cubic Number Fields
Jing Ma, Huayan Sun, Wenguang Zhai
Let K be a cubic number field. In this paper, we study the Ramanujan sums c_{J}(I), where I and J are integral ideals in O_{K}. The asymptotic behaviour of sums of c_{J}(I) over bo…
Left Derivations and Strong Commutativity Preserving Maps on Semiprime -Rings
Xiaowei Xu, Jing Ma, Yuan Zhou
In this paper, firstly as a short note, we prove that a left derivation of a semiprime -ring must map into its center, which improves a result by Paul and Halder and som…
