Good resources for integrals in Four-Space?

Click For Summary
Resources for integrals in four-space, particularly in the context of special and general relativity, are being sought, with a focus on practical applications rather than abstract mathematics. Key types of integrals mentioned include line elements, surface integrals, hypersurface integrals, and 4-D volume integrals. Landau-Lifgarbagez's field theory book offers a brief introduction, but more clarity is desired beyond mere formulas. Suggestions include exploring Eric Poisson's notes and his book "A Relativist's Toolkit," which cover relevant mathematical concepts. The discussion also touches on the relevance of differential forms and generalizations of Stokes and Gauss' theorems in higher dimensions.

I've been looking for some good resources on integrals in four-space (SR and GR), and hope someone can suggest some! I'm not too interested in abstract mathematical formalisms to the extent of pure math though, I must keep in mind that this is all to do with physics (at least for me!).

I know there are 4 kinds of integrals one can do in four-space:

(1) Integrate a line element, ie. a curve.
(2) Surface integral on a 2-D surface.
(3) Integral on a 3-D hypersurface.
(4) 4-D volume integral.

Landau-Lifgarbagez gives a brief intro in their field theory book but I'd like to clear some things up instead of just having formulae presented to me.

Any suggestions?

Cheers guys!

Could anyone even tell me what area of math these fall under? Including such things as generalizations of Stokes and Gauss' theorems to hifger dimensions.
 
You should read about differential forms, but you have voiced a non-interest in "mathematical formalism", so you may well be stuck.
 
For general relativity, I think some of what you want is in sections 3.1, 3.2, and 3.3 from Eric Poisson's notes,

http://www.physics.uoguelph.ca/poisson/research/agr.pdf,

which evolved into the excellent book, A Relativist's Toolkit: The Mathematics of black hole Mechanics.
 
In an inertial frame of reference (IFR), there are two fixed points, A and B, which share an entangled state $$ \frac{1}{\sqrt{2}}(|0>_A|1>_B+|1>_A|0>_B) $$ At point A, a measurement is made. The state then collapses to $$ |a>_A|b>_B, \{a,b\}=\{0,1\} $$ We assume that A has the state ##|a>_A## and B has ##|b>_B## simultaneously, i.e., when their synchronized clocks both read time T However, in other inertial frames, due to the relativity of simultaneity, the moment when B has ##|b>_B##...
