A side question. Can one be a bit more specific about what ##\lambda## is? He says that it doesn't matter and it could be many things, and he treats it as a single continuous variable, but then he integrates over it. So whatever the set of lambdas is, it has to be at least a measure space, no?In this paper, the locality assumption is "the vital assumption" after Eq. (1).
