THE SUB-LWNER PARTIAL ORDER OF METAPOSITIVE SUBDEFINITE MATRIX
Guo Wei · Journal of Mathematics · 2008
In this paper,the sub-Lwner partial order for submatrices of metapositive subdefinite matrix are discussed. By using these subpartial order,a few necessary and sufficient conditions that determine metapositive subdefinite of higher order matrices by metapositive subdefinite of lower order matrices are given.
