調和数・一般化調和数の定義
調和数・一般化調和数の定義
調和数・一般化調和数を次で定義する。
\[ H_{n}:=\sum_{k=1}^{n}\frac{1}{k} \] で表される。
\[ H_{n,m}:=\sum_{k=1}^{n}\frac{1}{k^{m}} \] で表される。
調和数・一般化調和数を次で定義する。
(1)調和数
1から\(n\)までの自然数の逆数の和を調和数といい、\[ H_{n}:=\sum_{k=1}^{n}\frac{1}{k} \] で表される。
(2)一般化調和数
1から\(n\)までの自然数の逆\(m\)乗の和を一般化調和数といい、\[ H_{n,m}:=\sum_{k=1}^{n}\frac{1}{k^{m}} \] で表される。
調和数と一般化調和数の間には
\[ H_{n,1}=H_{n} \] の関係がある。
