Query: A generalized Schwarz lemma for two domains related to $\mu$-synthesis   We present a set of necessary and sufficient conditions that provides a
Schwarz lemma for the tetrablock $\mathbb E$. As an application of this result,
we obtain a Schwarz lemma for the symmetrized bidisc $\mathbb G_2$. In either
case, our results generalize all previous results in this direction for
$\mathbb E$ and $\mathbb G_2$.
