Abstract
Donadi and Hossenfelder claim to have constructed a novel path integral over Hilbert space that reproduces quantum mechanics exactly. We contend that this claim is untenable, as they have given merely a definition of a certain quantity (which they call a path integral) without any way of actually calculating it.
期刊介绍:
Annals of Physics presents original work in all areas of basic theoretic physics research. Ideas are developed and fully explored, and thorough treatment is given to first principles and ultimate applications. Annals of Physics emphasizes clarity and intelligibility in the articles it publishes, thus making them as accessible as possible. Readers familiar with recent developments in the field are provided with sufficient detail and background to follow the arguments and understand their significance.
The Editors of the journal cover all fields of theoretical physics. Articles published in the journal are typically longer than 20 pages.
