Abstract
In this paper matrices
A
are considered that have the property that
A∗HA = H
,where
H
=
H∗
is invertible. A canonical form is given for the pair of matrices
(A,H)
under transformations
(A,H)
→
(
S−1AS,S∗HS), where
S
is invertible, in which the canonical form for the
A
-matrix is the usual Jordan canonical form. The real case is studied as well
