Fixed points in history
In mathematics, a fixed-point theorem is a result saying that a function F will have at least one fixed point (a point x for which F(x) = x), under some conditions on F that can be stated in general terms. Some authors claim that results of this kind are amongst the most generally useful in mathematics. WebApr 7, 2024 · Fixed points of the RG are scale-invariant QFTs: they look the same at all scales. If you start with some generic QFT and follow the RG flow to its low- or high-resolution limit, the usual expectation is that it approaches a scale-invariant QFT (if the limit is defined at all).
