On Symmetries in Nonlinear Quantum Mechanics
arXiv:quant-ph/9910012
Abstract
It is shown how nonlinear versions of quantum mechanics can be refolmulated in terms of a (linear) C*-algebraic theory. Then also their symmetries are described as automorphisms of the correspondong C*-algebra. The requirement of "conservation of transition probabilities" is discussed.
