Singular value inequalities on 2 x 2 block accretive partial
transpose matrices
Zhuo Huang
ABSTRACT: A 2 ? 2 block matrix
A X
Y
? B
is accretive partial transpose (APT) if both
A X
Y
? B
and
A Y ?
X B
are
accretive. This article presents some singular value inequalities related to this class of matrices. Our results complement
the presented inequality in [Oper Matrices 9 (2015):917?924].
