Jean-Michel Vappereau — Démonstration du théorème majeur de Lacan

This article is unlinked on the JMV site. It may have belonged to an original “annex” for the text 4≠3. If this is correct, there are two versions of this text, the first published 2 May 2012, the second on 23 October 2014. Either way, this work defines the mathematical basis of what Vappereau identifies as “the major theorem of Lacan.”
