| Mar 11, 2016 at 5:04 | comment | added | Fedor Petrov | We express everything via $A_\lambda$, as you suggest in the end of your post. $\lambda_n=(n-1)x_n+x_1+\dots+x_{n-1}$, substitute this and use your first 'elementary identity' | |
| Mar 11, 2016 at 4:46 | comment | added | Fedor Petrov | no, I do not care on how lambdas are ordered, that is why $i=n$ is generic case. | |
