Calculation of local formal Fourier transforms
arXiv:1011.3525
Abstract
We calculate the local Fourier transforms for connections on the formal punctured disk, corroborating the results of J. Fang and C. Sabbah using a different method. Our method is similar to Fang's, but more direct.
Added references, corrected lemma and added a case to proof of theorem, added clarity in proof of (13) implies (14) from version 1, fixed typos
