It is a real pleasure to acknowledge many stimulating and very helpful discussions with L. Nottale, G. Schumacher and J. Gay. The author is also grateful to J.M. Lecontel and D. Sornette for having suggested the present link between his Nonlinear Quantum Mechanics and Nottale's Scale Relativity Theory. He would like to express special thanks to the Referee for his (her) pertinent criticism and improvement of the manuscript. Finally he acknowledges the hospitality of the Department of Mathematics at the University of California-Santa Barbara where this work was initiated.
