Generalizations of Buzano inequality for \(n\)-tuples of vectors in inner product spaces with applications
The author establishes some generalizations of the Buzano inequality for \(n\)-tuples of vectors in inner product spaces. Applications for norm and numerical radius inequalities for \(n\)-tuples of bounded linear operators and for functions of normal operators defined by power series with non-negative coefficients are also discussed.
