A. For arbitrary n 2 N and x1; · · · ; xn 2 X we study the so-called n × n
Gram matrix [hxi; xji] with entries in A ; construct a non-decreasing sequence
of positive matrices in Mn(A) which is majorized by [hxi; xji] and apply it to
obtain generalizations of covariancevariance inequality; an extension of the Ostrowski
inequality and an improvement of the Kantorovich inequality involving
