In Section 3 it is shown that the same situation holds for the nonnegative P0-matrix completion problem, that is, a pattern for n × n matrices that includes all diagonal positions

Finally, we note that by the nature in which this proof discovers the inertially arbitrary patterns, starting with the ones with the fewest entries, (and the fact that no pattern in
In this paper, using the maximal rank of the generalized Schur complement, a new simpler equivalent condition is obtained in terms of only the ranks of the known matrices for
Criteria for existence of Hamiltonian quaternionic matrices that are square roots of a given skewHamiltonian quaternionic matrix are developed.. The criteria are formulated in terms
We include a Matlab program to generate Krein spaces numerical ranges of arbitrary complex matrices that treats the degenerate cases and represents the boundary generating curves..
Following the result of Feingold and Varga, a well-known theorem of Taussky on the eigenvalue distribution is extended to block diagonally dominant matrices and block H − matrices
