In mathematics, the class of Muckenhoupt weights consists of those weights for which the Hardy–Littlewood maximal operator is bounded on . Specifically, we consider functions on and their associated maximal functions defined as : where is the ball in with radius and centre . Let , we wish to characterise the functions for which we have a bound : where depends only on and . This was first done by Benjamin Muckenhoupt. ==Definition== For a fixed , we say that a weight belongs to if is locally integrable and there is a constant such that, for all balls in , we have : where is the Lebesgue measure of , and is a real number such that: . We say belongs to if there exists some such that : for all and all balls . 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「Muckenhoupt weights」の詳細全文を読む スポンサード リンク
