We have the stable choice [1]} (after replacing \(\beta \)  by \(-\beta \) )
\(\mathfrak {G}_{w_0}(X,Y)=\beta ^{-\ell (w_0)}\prod _{i+j\le n} \big (1-\mbox{$\frac{Y_i}{X_i}$}\big )=\prod _{i+j\le n} \frac{x_i-y_j}{1-\beta y_j}. \) 

У нас есть стабильный выбор [1] (после замены \(\beta \) на \(-\beta \))

\(\mathfrak {G}_{w_0}(X, Y) = \beta^{-\ell (w_0)} \prod_{i+j\le n} \big(1-\frac{Y_i}{X_i}\big) = \prod_{i+j\le n} \frac{x_i-y_j}{1-\beta y_j}.\)
