In mathematics, the Borell–Brascamp–Lieb inequality is an integral inequality due to many different mathematicians but named after Christer Borell, Herm Jan Brascamp and Elliott Lieb. The result was proved for ''p'' > 0 by Henstock and Macbeath in 1953. The case ''p'' = 0 is known as the Prékopa–Leindler inequality and was re-discovered by Brascamp and Lieb in 1976, when they proved the general version below; working independently, Borell had done the same in 1975. The nomenclature of "Borell–Brascamp–Lieb inequality" is due to Cordero-Erausquin, McCann and Schmuckenschläger, who in 2001 generalized the result to Riemannian manifolds such as the sphere and hyperbolic space. ==Statement of the inequality in R''n''== Let 0 < ''λ'' < 1, let −1 / ''n'' ≤ ''p'' ≤ +∞, and let ''f'', ''g'', ''h'' : R''n'' → [0, +∞) be integrable functions such that, for all ''x'' and ''y'' in R''n'', : where : Then : (When ''p'' = −1 / ''n'', the convention is to take ''p'' / (''n'' ''p'' + 1) to be −∞; when ''p'' = +∞, it is taken to be 1 / ''n''.) 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「Borell–Brascamp–Lieb inequality」の詳細全文を読む スポンサード リンク
