I agree Thom’s work is interesting and relevant here; I’ve seen it bruited about a lot, but likewise haven’t gotten around to seriously studying it. From my perspective, structural stability is extremely important, but I am curious if there is any reason to identify this kind of stability with catastrophes? I’ve always looked at the classification and figured its just one example of this kind of structural stability, and not one I’ve really even seen much of in physics, compared to the I-think-close-but-not-exactly-the-same more general idea of critical phenomena and phase transitions. I’d be very interested if there was some sort of RG-based stability analysis.
