In the talk we shall present some recent work done in collaboration with L. Escauriaza, C. E. Kenig and G. Ponce on a new approach to the celebrated result of G.H. Hardy that establishes that if a function and its Fourier transform decay faster than a precise gaussian they have to be identically zero. This new approach does not make use of the theory of analytic functions what allows for some interesting generalizations. The talk will be given in Spanish with slides in English.
