The paper studies the eigenvalue distribution of Schur complements of some special matrices, including nonstrictly diagonally dominant matrices and general H − matrices.. Zhang, Xu,
None of the usual floating point numerical techniques available for solving the quadratic matrix equation AX 2 + BX + C = 0 with square matrices A, B, C and X , can provide an
For a Hermitian matrix with its main block diagonal given, this paper shows how to choose the off-diagonal blocks such that the resulting matrix has the maximal and minimal

In the case N < ∞ it might also be tempting to conjecture that if H ( N ) is irreducible, and we move one (perpendicular) diagonal of 1’s closer to the main (perpendicular)
Applying this result to the matrix A/α , some properties on diagonal dominance and nonsingularity for the matrix A/α d will be presented to establish some results about the
A real matrix with nonnegative entries and having a largest eigenvalue of multiplicity just one has a strictly positive left eigenvector (see the Appendix) if and only if there
For a zero-delayed random walk on the real line, let τ (x), N(x) and ρ (x) denote the first passage time into the interval (x, ∞ ), the number of visits to the interval ( −∞ , x]
