Uncertainty principles for fractional Fourier transforms

 This talk is based on the article by Philippe Jaming [1] concerning uncertainty principles for fractional Fourier transforms.

The article is of didactic character and presents a systematic way of generalizing any uncertainty principle for a function and its Fourier transform to an equivalent uncertainty principle for two fractional Fourier transforms, provided the associated 'angle' between the two transforms is not a multiple of π (in the classical setting, the angle is π/2).

We will go through these generalizations from the point of view of metaplectic operators and discuss what happens in higher dimensions.
