Need help with Weinberg's QFT-Space inversion and time-reversal

    Need help with Weinberg's QFT---Space inversion and time-reversal

    Weinberg's Quantum Theory of Fields VI.

    Page 78. He gave the last equation but he didn't prove it, although he qualitatively explained it. I tried to prove it quantitatively but I failed.

    Also, in page 80, he didn't prove the first equation either. I need help with those two equations.

    The two pictures are from Google http://books.google.com/books?id=Nc...ce=gbs_ge_summary_r&cad=0#v=onepage&q&f=false
