摘要：
In this paper, vector norm inequalities that provides upper bounds for the Lipschitz quantity parallel to f (T) x - f (V) x parallel to for power series f(z) = Sigma(infinity)(n=0) a(n)z(n), bounded linear operators T,V on the Hilbert space H and vectors x epsilon H are established. Applications in relation to Hermite-Hadamard type inequalities and examples for elementary functions of interest are given as well.
