Query: The Heisenberg Relation - Mathematical Formulations   We study some of the possibilities for formulating the Heisenberg relation of
quantum mechanics in mathematical terms. In particular, we examine the
framework discussed by Murray and von Neumann, the family (algebra) of
operators affiliated with a finite factor (of infinite linear dimension).
