. The elementary methods (that is, the use of real analysis vs. complex analysis) have a long history from Chebyshev to modern times. They lead to great achievements, due to Erdos, Selberg, Bombieri, etc. I recently started a thorough study of these methods, in order to understand their scope. In the talk, I will give a quick survey of this field, and some new observations. Go to the Laboratoire Poncelet home page. Site design by Paul Zinn-Justin

... One of the most widely used tools of Fourier analysis is the Parseval theorem. It enables the experimentalist to view how the `energy' in the signal is distributed among frequencies. The Fast Fourier Transform (FFT) algorithms have made power spectra one of the obvious diagnostics tools during data acquisition, and energy maps are a versatile alternative. ... The result is an energy map (Fig. 9), showing the distribution of energy corresponding to the wavelet map (Fig. ...
