Dragomir, Sever S and Moslehian, M (2008) Some inequalities for (alpha, beta)-normal operators in Hilbert spaces. Facta Universitatis. Series Mathematics and Informatics, 23. pp. 39-47. ISSN 0352-9665
Abstract
In this paper we establish various inequalities between the operator norm and the numerical radius of (alpha, beta)-normal operators in Hilbert spaces. For this purpose, we employ some classical inequalities for vectors in inner product spaces.
