Abstract:

Let A,B be two positive semidefinite selfconjugate quaternion matricesof order n,“≤〖DD(〗L〖DD)〗” be the L[AKo¨D]wner partial ordering. Inthis paper, the author gives five characterizations of A≤〖DD(〗L〖DD)〗B and two characterizations of A\+2≤〖DD(〗L〖DD)〗B\+2, and also generalizes Liski's  result on L[AKo¨D]wner partial ordering of Hermitian matrices to the quaternion field.

Key words: wner partial ordering, Positive semidefinite selfconjugate quaternion matrix, Selfconjugate quaternion matrix, Square of quaternion matrx, Right eigenvalue
