| Jun 18, 2012 at 7:57 | comment | added | N. Virgo | @Chris I am indeed looking for a formal, mathematical definition, but autocatalysis is a chemistry concept, not a mathematical one, and therefore if a formal definition does exist it will be in the chemistry literature. | |
| Jun 18, 2012 at 0:46 | comment | added | Chris | The way this question is put is very curious, especially when you say "formal definition." You make it sound like you want something more mathematical. This is too obscure of an interest to have much luck in chemistry, so you'd probably have more luck on math.stackexchange.com | |
| Jun 12, 2012 at 16:06 | comment | added | Nick | @Nathaniel The definition of a chain reaction I saw as an undergrad (which excludes A->B, B->C) Is that a chain reaction has to include chain initiating steps, chain propagation steps, and chain termination steps. You can then define your elemental reactions in terms of these three categories, possibly overlapping if you have more than one chain carrier. This excludes intermediates such as A->B, B->C but includes A->B, B+C->D+B, B->A. Chain carriers are produced in initation/termination steps and bystanders in propagation steps. | |
| Jun 7, 2012 at 14:27 | comment | added | N. Virgo | I don't know if there's a formal difference, but the two concepts are clearly very closely related. I tend to think autotcatalysis is a more technically well-defined thing, since "chain reaction" can also refer to less interesting "chains" of reactions such as $A \to B$ together with $B \to C$. But if there's a good formal definition of a chain reaction in the self-amplifying sense, I'd be very interested to see it. | |
| Jun 7, 2012 at 13:37 | comment | added | Nick | Is there a formal distinction between a chain reaction, and an autocatalysed reaction? Both involve the creation of temporary species which are accumulate before being used to create product. | |

| May 7, 2012 at 16:01 | comment | added | N. Virgo | @LordStryker thanks! It's based on Kauffman's RAF sets though (Stuart Kauffman is the third author), whose definition relies on all the catalytic reactions being single-step ones. So it doesn't provide what I'm looking for, but it certainly looks interesting. | |
| May 7, 2012 at 15:57 | comment | added | LordStryker | Likely not a direct answer to your question but I'll leave it in a comment for the sake of awareness and perhaps discussion (and just popped up on my feed this morning). This paper looks interesting with regards to autocatalysis. arxiv.org/pdf/1205.0584v2.pdf | |
