Note : Lorentz Transform

Can this transformation can be written as the composition of an homotethy with a pure shearing ?

(i made a mistake with verbs in the last post).

 

I had a 2nd question : if one computes the norm of the changed basis vectors it founds [math]\gamma\sqrt{1+\beta^2}[/math] ?

Im dumb... it was just the metric (or i coord) to get 1.

 

Anyhow i couldnt find the definition of a shear matrix : can it be symmetric w/out 1s on the diagonal ?
