Different subsystems will have different dynamics, so the choice of division into subsystems will yield different subsystems and hence...

Assuming the Wigner superobserver performs some recoherent operation analogous to a quantum eraser experiment: If by "Does a division...

@JesseM Division events are nomolgical. They are features of dynamical laws. Supernatural entities like the Wigner superobserver don't...

This amounts to a choice of subsystem to model. Like in textbook QM, you can decide what subsystem to model, but it isn't an issue* in...

Section 3.7 in https://arxiv.org/pdf/2302.10778 outlines how. It is very closely related: If a system has become correlated with its...

Division events fall out of the formalism, and nothing in the formalism depends on a choice of realizer.

Basically yes.

Assertions like "stochastically switching until measured" or "switching with frequency X" aren't addressed by the formalism because they...

Here's what Barandes says specifically: "Given just the minimalist ingredients that define a given indivisible stochastic process, there...

Yes in the narrow sense that the dynamics do not supply the conditional probabilities needed to say whether or not such a transition can...

Yes, the configuration space in the papers is the space of spatial arrangements. I think this is the same as in Bohmian mechanics but I...

David Wallace, an established many-worlds champion, draws heavily from the decoherent histories formalism to sketch the notion of a...

Unless I am misunderstanding, take some configuration ##i##: ##p_i(t) = \sum_j \Gamma_{ij}(t\leftarrow t_0)p_j(t_0)##. This is equation...

Griffiths CH is the most explicitly realist version of CH among the developers of the formalism. His writings on it are also the most...

Projection to any configuration space produces the non-Markovianity, particles or fields. Barandes uses particle configurations, so I...
