Just to be clear the Cauchy Stress tensor is actually a ##(1,1)## tensor so ## T: V\times V^* \to \mathbb R##. So no isomorphism is...

Homogeneity of space means invariance under purely spatial translations. Thus if you have two events whose coordinates are ##x_a##...

I want to elaborate on my previous post. Imagine the game is changed. You have three doors, one, with a car behind it. Now you can...

It's really simple. Would you rather get to pick 2 doors or 1. By switching you are essentially getting to look behind the two doors you...

see https://arxiv.org/abs/2607.24825 for details

There are critiques of this argument similar to this, see https://arxiv.org/abs/quant-ph/0312058?hl=en-US . Not sure how accepted...

This Zurek paper explains in more detail how you get multiple different decoherent branches, https://arxiv.org/abs/quant-ph/0405161 ...

I am not aware of a way to in general fix this integral in the sense that there is a unique 1:1 correspondence between this integral and...

Yes, but that choice is path dependent. Any two tangent spaces at ##p_1,\, p_2## can be made isomorphic via the connection if you...

Yeah, I think in general you need some vector field to "ground" you as you move around the manifold. In my post #3 I suggested using a...

Yes, I guess that's true. Now, I think you need some preferred basis of some kind.

Ah got it, I was not familiar with this terminology. Hadn't realized this. Interesting point. Given the basis exists on ##D##, how...

And the Bohmian Rhpsody.

Two branches are considered distinct if they are decohered. Do you understand that concept? Not sure I can explain it in a few words but...

I haven't had a chance to reread this in detail but I believe this paper by Zurek discusses it, https://doi.org/10.1103/PhysRevA.71.052105
