# The Wallstrom objection as a possibility to augment quantum theory

@article{Schmelzer2019TheWO, title={The Wallstrom objection as a possibility to augment quantum theory}, author={Ilja Schmelzer}, journal={arXiv: Quantum Physics}, year={2019} }

Wallstrom has argued that quantum interpretations which construct the wave function starting from Madelung variables $\psi(q)=\rho(q)\exp(\frac{i}{\hbar}S(q))$, in particular, many variants of Nelsonian stochastics, are not equivalent to quantum theory. Accepting this, we explicitly add the physical restriction $(\forall q\in Q)|\psi(q)|^2>0$ in the configuration space representation to quantum theory. The resulting theories depend on the choice of the configuration space $Q$.
The restriction…
