D. Hershkowitz et al., APPROXIMABILITY BY WEIGHTED NORMS OF THE STRUCTURED AND VOLUMETRIC SINGULAR-VALUES OF A CLASS OF NONNEGATIVE MATRICES, SIAM journal on matrix analysis and applications, 18(1), 1997, pp. 249-257
A known result about the spectral radius of an irreducible nonnegative
matrix is extended to all nonnegative matrices. By means of this resu
lt, it is shown that the structured singular value and the Volumetric
singular Value of a class of nonnegative matrices can be approximated
with arbitrary accuracy by the matrix norm induced by a weighted l(2)
vector norm and in the simplest case by a weighted l(p) vector norm fo
r any p.
