#### 1.3.2.4.4.4. Symmetry property

| top | pdf |

A final formal property of the Fourier transform, best established in , is its symmetry: if f and g are in , then by Fubini's theorem

This possibility of `transposing' (and ) from the left to the right of the duality bracket will be used in Section 1.3.2.5.4 to extend the Fourier transformation to distributions.
