The term "Lorentz transformations" only refers to transformations between inertial frames.
However, if we differentiate velocity with respect to time, we obtain acceleration.
The Lorentz factor says:
t(0 reference frame observer at rest) / t(moving) = 1 / Sqrt[1–(v/c)^2]
t0 / tm = 1/[(1-(v/c)2]1/2
If we want t(moving) to be changing then we need to differentiate the lorentz factor with respect to t(moving)
v is a function of t so
t0 / taccelerating = ∂ (1/ [(1-(v(t) / c)2]1/2) ∂t
t0 / taccelerating = (v[t] ∂v[t]/∂t) / (c2 (1 - v[t]2/c2])3/2]
It looks better here:
https://www.wolframalpha.com/input/?i=differentiate+1/(1-(v(t)/c)^2)^1/2
so the calculation would require we know the acceleration AND velocity at the moment we want to know what the time dilation is doing.
Although we can do the mathematical gymnastics, I do not know if there are any assumptions in the derivation of the Lorentz transformation that REQUIRE an inertial frame.
Or is the equation above really valid?
