| Jan 31 at 3:08 | comment | added | Michael Engelhardt | I don't know about "It is usually said ...". What I hear usually said among physicists is that in the path integral, the set of smooth functions is of measure zero, and the integral is dominated by rough paths. Smooth paths maybe if you're doing a semiclassical approximation. | |
