Sharp upper and lower bounds for the spectral radius of a nonnegative irreducible matrix
Lihua You, Yujie Shu, Pingzhi Yuan
In this paper, we obtain the sharp upper and lower bounds for the spectral radius of a nonnegative irreducible matrix. We also apply these bounds to various matrices associated wit…
