Hello, I have probably quit easy task, but I don't know how show that d3x d3p is a Lorentz invariant.
Homework Equations
The Attempt at a Solution
I mean I have to show that d3x d3p = d3x' d3p', where ' marks other system. I can prove ds2=ds'2, but I am not sure what with p?
Assume boost in x-way:
x'=g(x-vt) => dx'=g(dx-vdt) , where g=1/(1-(v/c)2)...is it right?
what about p?
