Around 1986, Colin McLarty, Charles Wells, and I noticed that Scientific American had recently published a few articles on subjects mathematical and decided to try to write one on variable set theory, AKA topos theory. Unfortunately, that particular window at Sci Am quickly closed. Our article was turned down and we forgot about it. More recently, I decided it might be interesting, or at least amusing to throw it open to the categorical community.

Dear categoricists, It is well known that higher category theory has applications in homotopy (Work of Joyal, Lurie, Grothendieck conjecture, etc.). May someone gives me some references about probable applications of higher category theory in other areas ? I guess in computer science and other areas (rewriting ? etc.), they are probably some works !? Thank you very much to give me these references and for your help ! Best regards, Camell.

A couple of general articles, somewhat speculative, are available from my publication list: http://pages.bangor.ac.uk/~mas010/publicfull.htm 130.(with T. PORTER), `The intuitions of higher dimensional algebra for the study of structured space', Revue de Synth?se, 124 (2003) 173-203. ` UWB Math. Preprint (pdf file) <pdffiles/paris-cogn9.pdf>. 136. (with T. Porter), `Category theory and higher dimensional algebra: potential descriptive tools in neuroscience', Proceedings of the International Conference on Theoretical Neurobiology, Delhi, February 2003, edited by Nandini Singh, National Brain Research Centre, Conference Proceedings 1 (2003) 80-92. pdf <pdffiles/brown-porter03_05.pdf> You should also look at the area of concurrency theory. Running many computers is analogous to many dimensional time. And do a web search on "higher dimensional algebra" with for example physics, biology, ...
