As a comment of Dennis Serre, the correct spelling of Cauchy-Schwarz is Cauchy-Schwarz (not Cauchy-Schwartz):
The spelling is Cauchy-Schwarz, from Hermann Schwarz. If you are interested in Fourier transform and distributions instead, then you probably mean Laurent Schwartz.
A simple search gives us 72 results for Cauchy-Schwartz in MO, see here. Is there a way to correct this misspelled word without bumping? Or should an ordinary user correct this misspelled word?
