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

Our rank certificate can also be applied for certifying the rank of sparse or structured integer matrices using the black box approach.. Indeed the techniques we have presented can
Of particular interest is the connection between this standard inverse eigenvalue problem and describing all the possible associated ordered multiplicity lists, along with
The class of symmetric real matrices having exactly one pos- itive eigenvalue will be denoted by B.. The class of positive matrices belonging to B will be denoted by A ;
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
First we note that the construction of the A -process for all time is trivial, since the A -particles by themselves merely perform independent continuous time simple random walks..
More precisely it was shown that, when the Markov transition matrix on each branch satisfies the Kesten-Stigum bound, the phylogeny can be reconstructed in polynomial time
