On the denominators of harmonic numbers
Bing-Ling Wu, Yong-Gao Chen
Let be the -th harmonic number and let be its denominator. It is well known that is even for every integer . In this paper, we study the properties of…
Diophantine equations involving Euler's totient function
Yong-Gao Chen, Hao Tian
In this paper, we consider the equations involving Euler's totient function and Lucas type sequences. In particular, we prove that the equation has no solu…
On a problem of Nathanson
Yong-Gao Chen, Min Tang
A set of nonnegative integers is an asymptotic basis of order if every sufficiently large integer can be represented as the sum of integers (not necessarily distinct) o…
On - covering sequences
Yong-Gao Chen
Recently, motivated by Stanley sequences, Kiss, S\' andor and Yang introduced a new type sequence: a sequence of nonnegative integers is called an - covering sequence if…
