A Gravitational anomalies in gauge theory

  1. Oct 17, 2017 #1
    Dear All
    Can anyone explain for me what is meant by gravitational anomalies in gauge theory?
    What is the difference between it and gauge anomalies?
    Thank you

    My first guess would be that gravitational anomalies arise in effective field theories of quantum gravity (quantization of GR) in triangle diagrams, which analogously to "normal" gauge anomalies in Yang-Mills theories threaten to spoil your gauge symmetry: the invariance under general coordinate transformations.
