متن کاملSome Reverses of the Cauchy––schwarz Inequality for Complex Functions of Self–adjoint Operators in Hilbert Spaces
We give some ratio and difference reverses of the Cauchy–Schwarz inequality for complex functions of self-adjoint operators in Hilbert spaces, under suitable assumptions for the involved operators. Several examples for particular functions of interest are provided as well. Mathematics subject classification (2010): 47A63, 47A99.
