"Dual spaces and von Neumann Algebras"
A
canonical
construction
in
Linear
Algebra
is
that
of
the
dual
space.
In
this
talk,
we
consider
two
questions:
When
is
a
Banach
space
a
dual
space?
When
is
there
only
one
possible
predual?
Examples will be presented illustrating that these are not trivial questions, and a major theorem (Sakai's) will be presented giving a broad class of examples for the second question.
