Abstract

We will introduce the https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F15063/MediaObjects/13660_2004_Article_1568_IEq2_HTML.gif times modified centered and uncentered Hardy-Littlewood maximal operators on nonhomogeneous spaces for https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F15063/MediaObjects/13660_2004_Article_1568_IEq3_HTML.gif . We will prove that the https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F15063/MediaObjects/13660_2004_Article_1568_IEq4_HTML.gif times modified centered Hardy-Littlewood maximal operator is weak type https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F15063/MediaObjects/13660_2004_Article_1568_IEq5_HTML.gif bounded with constant https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F15063/MediaObjects/13660_2004_Article_1568_IEq6_HTML.gif when https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F15063/MediaObjects/13660_2004_Article_1568_IEq7_HTML.gif if the Radon measure of the space has "continuity" in some sense. In the proof, we will use the outer measure associated with the Radon measure. We will also prove other results of Hardy-Littlewood maximal operators on homogeneous spaces and on the real line by using outer measures.
