| Nov 1, 2014 at 22:48 | comment | added | Ricardo Andrade | Please do not quickly post questions on both MathOverflow and Math.StackExchange, as it is frowned upon by both communities. Please pick one of the sites, wait at least a few days for an answer and only then ask to migrate the question. | |

Change notation for elementary symmetric functions from $s_k$ to $e_k$ and added definition.

| Nov 1, 2014 at 18:41 | comment | added | Suvrit | So in other words, this is $\prod_l\det(P_l)$, where $P_l$ is a diagonal matrix with entries $[1+x_l+y_i]_{i=1}^n$; i.e., $\det(P_1\cdots P_m)$. But expanding out the products seems to not be so cool; perhaps working with $\sum_{kl}\log ...$ may be more helpful. | |

| Nov 1, 2014 at 18:25 | comment | added | Alex Degtyarev | Just a thought: by the splitting principle, an expression you're seeking for would compute the Stiefel-Whitney/Chern/Pontrjagin classes of the tensor product of two bundles in terms of those of the factors. Obviously, lots of people thought about this but, AFAIK, no nice closed formula is known. | |
