Description
It is reassuring to be able to get the same answer with two different methods, and indicates that we really understand the relevant physics. On the other hand, when two methods don't agree, at least one of them must be wrong. In the study of apparently weakly-coupled phase transitions there have been rather mixed results in matching lattice simulations against perturbation theory, suggesting that in places our understanding is lacking. In this talk, I'll present some overview of this saga, together with recent progress for some simple models.
