Talk:Combinatorial species

From Wikipedia, the free encyclopedia

It would help to know in what areas the term is used. It's linked to from Species - is "combinatorial species" a biological term also? Mathematical? Or both? Tannin

Actually, it didn't occur to me that I had not made that clear by using the word "combinatorial". But now I've made it more explicit. (For now, it's still only a stub article.) -- Mike Hardy

The description of the cycle index series seems slightly ambiguous. Namely, where is the dependence of \left( \sum_{\sigma \in S_A} |\mathrm{Fix}(F[\sigma])| x_1^{\sigma_1} x_2^{\sigma_2} \cdots \right) on n? - Gauge 02:15, 10 January 2006 (UTC)

PS. It would be nice to indicate if the theory of combinatorial species has solved some interesting new problems. Thanks. CW 16 February 2006
