Summation of Harmonic Numbers

1989
The problem of finding closed forms for a summation involving harmonic numbers is considered. Solutions for ∑ i n =1P(i)H i (k) , where p(i) is a polynomial, and ∑ i n =1 Hi/(i+m), where m is an integer, are given. A method to automate these results is presented.

On the denominators of harmonic numbers, II

Journal of Number Theory, 2019
The \textit{harmonic number} \(H_n\) is defined as \(\sum_{i=1}^n \frac{1}{i}\) and the \textit{alternating harmonic number} \(A_n\) is defined as \(\sum_{i=1}^n (-1)^{i+1}\frac{1}{i}\). Write \(H_n=\frac{u_n}{v_n}\) with \(\gcd(u_n,v_n)=1\), \(v_n>0\); and \(A_n=\frac{a_n}{b_n}\) with \(\gcd(a_n,b_n)=1\), \(b_n>0\).
