Cauchy identity in three sets of variables?
The Cauchy identity states that
$$
\prod_{i,j} \frac{1}{1-x_i y_j} = \sum_\lambda s_\lambda(x) s_\lambda(y),
$$
where $s_\lambda(x)$ is the Schur function.
Is there a known decomposition of the produ …

Representation Theory of $U(N)$
Regarding (2): In the context of rational complex representations of $GL_n$ vs those of $SL_n$, your extra factor is accounted for by the determinant. Given a rational representation of $GL_n$, $V$, i …
