A singular M-matrix perturbed by a nonnegative rank one matrix has positive principal minors; is it D-stable? (Elsevier, 2014)The positive stability and D-stability of singular M-matrices, perturbed by (non-trivial) nonnegative rank one perturbations, is investigated. In special cases positive stability or D-stability can be established. In full ...
