Upper bounds for $\|A^{-1}Q\|_\infty$
L. Yu. Kolotilina
St. Petersburg Department of Steklov Mathematical Institute of Russian Academy of Sciences
Abstract:
The paper suggests a general approach to deriving upper bounds for $\|A^{-1}Q\|_\infty$ from those for $\|A^{-1}\|_\infty$ for matrices $A$ belonging to different subclasses of the class of nonsingular $\mathcal{H}$-matrices. The approach is applied to SDD, $S$-SDD, OBS, OB, and Nekrasov matrices.
Key words and phrases:
$l_\infty$-norm of the inverse, upper bounds, SDD matrices, $S$-SDD matrices, OB matrices, OBS matrices, Nekrasov matrices, nonsingular $\mathcal H$-matrices.
