Sharp bounds on distance spectral radius of graphs

The version of this paper published online on 7 June 2012 (DOI: 10.1080/03081087.2012.689984) contained the following errors:

Lemma 2.1

If A is a nonnegative irreducible n × n matrix with spectral radius ϱ(A) and row sums s ₁, s ₂, … , s _n , then

Moreover, one of the equalities holds if and only if the row sums of A are all equal.

Lemma 2 should be replaced with the corrected version below:

Lemma 2.1

Moreover, one of the equalities holds if and only if the row sums of A are all equal.
