A Generalization of the Stone-von Neumann Theorem
to Non-Regular Representations of the  CCR-Algebra
(43K, TeX)

ABSTRACT.  We give a classification, up to unitary equivalence, of the
representations of the $C^*$-algebra of the Canonical
Commutation Relations which generalizes the classical
Stone-von Neumann Theorem to the case of representations
which are strongly measurable, but not necessarily
strongly continuous. The classification includes all
the (non-regular) representations which have been considered in
physical models.
