Generalizations of Buzano inequality for n-tuples of vectors in inner product spaces with applications

S. S. Dragomir

In this paper some generalizations of Buzano inequality for n-tuples of vectors in inner product spaces are given. 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 nonnegative coefficients are also provided.
