Abstract

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 weak τ strict contractions, and some continuity properties of these maps are discussed. We also discuss possible applications of our procedure to quantum mechanical systems.
