Hi,
I'm currently reading the book "Quantum Field Theory for Mathematicians" by Ticciati and in section 2.3 he mentions that the Lorentz action on the free scalar field creation operators
[itex] \alpha(k)^\dagger [/itex] is given by
[tex] U(\Lambda)\alpha(k)^\dagger U(\Lambda)^\dagger =
\alpha(\Lambda k)^\dagger .[/tex]
Can someone tell me how to show this, or at least how to get started?
