ON A DIFFERENCE BETWEEN QUANTITATIVE WEAK SEQUENTIAL COMPLETENESS AND THE QUANTITATIVE SCHUR PROPERTY
We study quantitative versions of the Schur property and weak sequential and continued by H. Pfitzner and the authors. We show that the Schur property of l(1 is quantitatively weakly sequentially complete, has the Schur pro...

ON CONDITIONING OF SCHUR COMPLEMENTS OF H-TFETI CLUSTERS FOR 2D PROBLEMS GOVERNED BY LAPLACIAN
Bounds on the spectrum of the Schur complements of subdomain stiffness matrices with respect to the interior variables are key ingredients in the analysis of many domain the estimates of the regular condition number of the Schur com...

Parallel Schur complements for mixed-hybrid discretization of fracture flow problem
We present an scalable parallel construction of Schur complements for the saddle-point problem arising from mixed-hybrid discretization of a linear of the Schur complements leads to significant improvements in total solution time. T...

Asymptotic stability of a full term linear difference equation with two parameters
The paper introduces an efficient form of necessary and sufficient conditions for a special full term linear difference equation with two real parameters to be asymptotically stable. The result is obtained utilizing the Schur-Cohn c...
