Abstract: The classical Riemann-Hilbert correspondence establishes an equivalence between the categories of regular holonomic D-modules and of perverse sheaves. In order to extend this correspondence to the irregular case, the target category has to be "enhanced". I will illustrate such enhancement, focusing on the one-dimensional case and the Fourier-Sato transform. (This is from joint works with Masaki Kashiwara.)
