The space of n-point correlation functions, for all possible time-orderings of operators, can be computed by a non-trivial path integral contour, which depends on how many time-ordering violations are present in the correlator.These contours, which have come to be known as timefolds, or out-of-time-order (OTO) contours, are a natural generalization …
