Abstract

The chaotic order https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F79123/MediaObjects/13660_2005_Article_1639_IEq1_HTML.gif among positive invertible operators https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F79123/MediaObjects/13660_2005_Article_1639_IEq2_HTML.gif on a Hilbert space is introduced by https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F79123/MediaObjects/13660_2005_Article_1639_IEq3_HTML.gif . Using Uchiyama's method and Furuta's Kantorovich-type inequality, we will point out that https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F79123/MediaObjects/13660_2005_Article_1639_IEq4_HTML.gif if and only if https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F79123/MediaObjects/13660_2005_Article_1639_IEq5_HTML.gif holds for any https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F79123/MediaObjects/13660_2005_Article_1639_IEq6_HTML.gif , where https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F79123/MediaObjects/13660_2005_Article_1639_IEq7_HTML.gif is any fixed positive number. On the other hand, for any fixed https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F79123/MediaObjects/13660_2005_Article_1639_IEq8_HTML.gif , we also show that there exist positive invertible operators https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F79123/MediaObjects/13660_2005_Article_1639_IEq9_HTML.gif , https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F79123/MediaObjects/13660_2005_Article_1639_IEq10_HTML.gif such that https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F79123/MediaObjects/13660_2005_Article_1639_IEq11_HTML.gif holds for any https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F79123/MediaObjects/13660_2005_Article_1639_IEq12_HTML.gif , but https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F79123/MediaObjects/13660_2005_Article_1639_IEq13_HTML.gif is not valid.
