| Jan 5, 2011 at 20:16 | comment | added | Qiaochu Yuan | @Zev: I don't think there's much more to say beyond what's in Stanley's answer. I also don't really think the twelvefold way is the right way to look at the vector space side of things; quantum mechanics seems to me a much better source of motivation, and it is also relevant to this supervector space stuff. I discuss this briefly at the end of my most recent blog post: qchu.wordpress.com/2011/01/02/… | |
| Jan 5, 2011 at 19:31 | comment | added | Zev Chonoles | Qiaochu, could you add this over on my question here: mathoverflow.net/questions/22750/… ? It sounds quite relevant. What are the power series (if there are any natural ones) that have the other pieces of the twelvefold way as their coefficients? | |
