In mathematics, and in particular the necklace splitting problem, the Hobby–Rice theorem is a result that is useful in establishing the existence of certain solutions. It was proved in 1965 by Charles R. Hobby and John R. Rice; a simplified proof was given in 1976 by A. Pinkus. ==The theorem== Given an integer ''k'', define a ''partition'' of the interval () as a sequence of numbers which divide the interval to subintervals: : Define a ''signed partition'' as a partition in which each subinterval has an associated sign : : The Hobby-Rice theorem says that for every ''k'' continuously integrable functions: : there exists a signed partition of () such that: : (in other words: for each of the ''k'' functions, its integral over the positive subintervals equals its integral over the negative subintervals). 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「Hobby–Rice theorem」の詳細全文を読む スポンサード リンク
