In path integrals, how does one deal with non-differentiable paths? Obviously non-differentiable paths are allowed, but with Feymann's formulation, one has to calculate the action for a path, and then sum over all possible paths. How is the action defined (if it is defined at all) for a non-differentiable path?
Also, is it possible to construct path integral vigorously by constructing a measure on the space of possible paths?
