"The
numerical
range
of
quaternion
matrices
with
respect
to
involutions"
In
this
talk,
we
study
some
algebraic
and
geometrical
properties
of
the
quaternionic
numerical
ranges
with
respect
to
involutions.
We
give
a
description
of
these
sets
for
2
by
2
matrices
and
also
for
$\phi$-hermitian
and
$\phi$-skew
hermitian
quaternion
matrices.
Finally,
we
state
some
examples
and
open
problems
about
the
numerical
range
of
quaternion
matrices
with
respect
to
non-standard
involutions.
