In mathematics, a nonlocal operator is a mapping that maps a space of functions on a topological space to another space of functions on some domain in such a way that the value of the function output at a given point cannot be determined solely from the values of the input function in an arbitrary neighbourhood of any point. An example of a nonlocal operator is the Fourier transform.
