Hi Doriano,
Welcome to the list.
You raise an interesting problem and. I don't know the answer to your
question. However, I just want to point out that an observer in relative
motion observes the rotation in the complex plane of space-time
geodesics. Could there be a connection between
The so-called Wick rotation which is often employed to turn the
unruly measure of path integrals into a regular summable measure
and is represented as
t --- -it
has no direct relation with the so-called Weyl unitarity trick
which is used to turn the bilinear anti-symmetric non-positive definite
Hi to everybody. I subscribed to this mailing list yesterday, but I'd
like to pose a question since I think it _must_ be the right place.
Quantum mechanics can be formulated in terms of path integrals (Feinmann
integrals). By substituting the time t with an (Euclidean) immaginary
time i s,
