Query: Fixed Points in Topological *-Algebras of Unbounded Operators   We discuss some results concerning fixed point equations in the setting of
topological *-algebras of unbounded operators. In particular, an existence
result is obtained for what we have called {\em weak $\tau$ strict
contractions}, and some continuity properties of these maps are discussed. We
also discuss possible applications of our procedure to quantum mechanical
systems.
