Which are the components of the Lorentz tensor in SR if the signature of the Minkowski metric is (-+++)? Can you give me a link to some page showing them? Thanks

Which Lorentz tensor? A Lorentz tensor is anything that transforms as a tensor under a Lorentz transformation.

Tom, I'm referring to the Lorentz tensor used to transform a displacement 4-vector from one frame of reference to another

 

The equation goes this way:

 

D=LD'

where L is the Lorentz tensor

aNYBODY?

I think the one your after, for transforming any 4 vector into another frame, is:

 

g -gb 0 0

-gb g 0 0

0 0 1 0

0 0 0 1

 

I had to use g = gamma factor and b = beta factor (beta = v/c) because I can't do all the fancy formulas and stuff that other people seem to be able to use.

Here you go:

 

 

 

[math] \left( \begin{array}{cccc}

\gamma \ \ \ -\gamma\beta \ 0 \ 0\\

-\gamma\beta \ \ \ \ \gamma \ 0 \ 0\\

0 \ \ \ \ \ \ \ \ 0 \ \ 1 \ 0\\

0 \ \ \ \ \ \ \ \ 0 \ \ 0 \ 1\\

\end{array} \right)

[/math]

 

Theres a bug in the Latex here, so I had to insert a bunch of spaces to get things in the right colums. Normally you just use the ampersand & to separate entries, but that feature isn't working right.

Geez, calm down! No one owes you an answer, and we all have real lives that sometimes get in the way of making 20 posts a day.

 

Well except for Johnny, apparently.

I'm at 22 a day, holy cow.

thanks johnny! always make things look so pretty
