View on Github →refactor(Analysis/Fourier): use AddChar
machinery in FourierTransform
(#11417)
The file Analysis/Fourier/FourierTransform.lean
predates the general approach to additive characters elsewhere in the library; this merges the two (getting rid of the rather kludgy notation e [x]
in the process). I also rejigged some slow proofs, to make them compile slightly faster.
