Amer Abu Omar, Fuad Kittaneh Studia Mathematica 216 (2013), 69-75 MSC: Primary 47A10, 47A12, 47A30, 47A63; Secondary 15A60, 47B15, 47B49. DOI: 10.4064/sm216-1-5

Streszczenie

A spectral radius inequality is given. An application of this inequality to prove a numerical radius inequality that involves the generalized Aluthge transform is also provided. Our results improve earlier results by Kittaneh and Yamazaki.
