Wolfgang Wildgen's "Catastrophe theoretical models in semantics"

John Sowa writing on the Ontolog discussion list 2007 (http://ontolog.cim3.net/forum/ontolog-forum/2008-02/msg00085.html):

"René Thom, who founded catastrophe theory and received the Fields
Medal for his efforts, was firmly convinced that all areas of human
perception and cognition -- language, in particular -- depend on
features that are closely related to catastrophe theory.

Wolfgang Wildgen is a linguist who developed Thom's ideas on
catastrophe theory applied to of semantics. For various papers
and PowerPoint slides (in English, German, and French) see
the list on his website:


Wildgen also published several books in English that present
Thom's ideas and Wildgen's extensions in some detail."
