- I would like to know if the following is true, and if it is, does anyone have
- a reference to a proof.
-
- Suppose f is in L^2(R) (square integrable over the reals) and tf^(t)
- is also in L^2(R), where f^ is the Fourier transform of f. Then f is
- differentiable a.e.

- I would appreciate replies by e-mail.
