Topic: A 'WorldVolume' directory


Joseph Tooby-Smith (Jun 19 2025 at 05:41):

A would like to argue for the following design decision:

That is to have a main directory called WorldVolume and within that directory move the current Space, Time and SpaceTime directories. Currently the two former ones are in ClassicalMechanics, and the latter is in Relativity. I would also like it to include things like compact versions of Time (e.g. circular) etc.

I understand that WorldVolume is a fairly niche name, and am happy to hear alternatives if people have them. The name WorldVolume comes from Sigma models where you have fields ϕ:ΣM\phi : \Sigma \to M, here Σ\Sigma is the WorldVolume and MM is the target space.

I'd be happy to hear any comments on this.

i think it's a cool name

I'm a bit concerned about people wouldn't know where to look for those definitions - but I don't know what alternative name would be suitable for the directory other than just calling it SpaceTime which may not be the best

Maybe SpaceAndTime?

Tomas Skrivan (Jun 20 2025 at 22:42):

I think it does not matter too much. Anytime you import almost anything from PhysLean you will import these files transitively.

This is done in PR624, went with SpaceAndTime for now, can always change later.
