Hello, everyone

I am studying Srednicki's "Quantum Field Theory", section 4 "The spin-statistics Theorem".

Does anyone know how to show that "The time ordering of two spacetime points

And "Two spacetime points whose separation is spacelike, can have different temporal ordering in different frames." How to show this?

Thanks

Does anyone know how to show that "The time ordering of two spacetime points

*x*and*x'*is frame*independent*if their separation is*timelike*."(P32),**explicitly**?And "Two spacetime points whose separation is spacelike, can have different temporal ordering in different frames." How to show this?

Thanks
