    Derivation of Integration in Spinfoam Model with SU(2) Measure and Intertwiners

    Thanks a lot! etera. I can understand almost all your statement except that Idon't know why the integration is the identity operator on V0. And by the way could you please tell me some useful book or reference about this. Thanks again!

    Derivation of Integration in Spinfoam Model with SU(2) Measure and Intertwiners

    Hi! Thanks for pay attention. I am learning spinfoam model through Rovelli's book and other reviews. I don't know how to perform the derivation of the integration: \int{dU R^{j1}(U)^{a}_{a'} R^{j2}(U)^{b}_{b'} R^{j3}(U)^{c}_{c'}=v^{abc}v_{a'b'c'}} the integration is over SU(2), the...
