Numerical Radius Inequalities for Finite Sums of Operators

Numerical Radius Inequalities for Finite Sums of Operators

In this paper, we obtain some sharp inequalities for numerical radius of finite sums of operators. Moreover, we give some applications of our result in estimation of spectral radius. We also compare our results with some known results.
