Schur complement-based infinity norm bounds for the inverse of S-Sparse Ostrowski Brauer matrices

Schur complement-based infinity norm bounds for the inverse of S-Sparse Ostrowski Brauer matrices

In this paper, we study the Schur complement problem of $ S $-SOB matrices, and prove that the Schur complement of $ S $-Sparse Ostrowski-Brauer ($ S $-SOB) matrices is still in the same class under certain conditions. Based on the Schur complement of $ S $-SOB matrices, some upper bound for the inf...
