On Numerical Radius of a Matrix and Estimation of Bounds for Zeros of a Polynomial
We obtain inequalities involving numerical radius of a matrix A∈Mn(ℂ). Using this result, we find upper bounds for zeros of a given polynomial. We also give a method to estimate the spectral radius of a given matrix A∈Mn(ℂ) up to the desired degree of accuracy.
