We argue that this is symptomatic of the fact that Quantum Theory is actually a theory in multiply connected space while Classical Theory operates in simply connected space.8 pages, tex, part of Chapter 5 of The Universe of Fluctuations, SpringerGeneral PhysicsQuantum Mechanics and Multiply Connected Spacestext
