In mathematics, the von Mangoldt function is an arithmetic function named after German mathematician Hans von Mangoldt. It is an example of an important arithmetic function that is neither multiplicative nor additive. ==Definition== The von Mangoldt function, denoted by , is defined as : The values of for the first nine positive numbers are : which is related to . The summatory von Mangoldt function, , also known as the Chebyshev function, is defined as : von Mangoldt provided a rigorous proof of an explicit formula for involving a sum over the non-trivial zeros of the Riemann zeta function. This was an important part of the first proof of the prime number theorem. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Von Mangoldt function」の詳細全文を読む スポンサード リンク
