Title: On the Fourier transform of BV functions
Abstract:
This talk is based on a joint work with Thomas Beretti (SISSA, Trieste). The plan is to introduce BV functions and the Fourier transform and study how this two objects interact. We will prove asymptotic formulae for the Fourier transform of BV functions and (as a corollary) for characteristic functions of sets of finite perimeter. Finally we will show how, using techniques of geometric measure theory, it is possible to sharpen some results of Herz, concerning convergence properties of the Fourier transform of sets. Time permitting, we will show some applications to the isoperimetric inequality and some open problems.
