Abstract
Lower-semi-Nekrasov matrices represent a generalization of Nekrasov matrices.
For the inverse of lower-semi-Nekrasov matrices, a max-norm bound is
proposed. Numerical examples are given to illustrate that new norm bound can
give tighter results compared to already known bounds when applied to
Nekrasov matrices. Also, we presented new max-norm bounds for the inverse of
lower-semi-Nekrasov matrices in the block case. We considered two types of
block generalizations and illustrated the results with numerical examples.
