Query: Lipschitz continuity of the dilation of Bloch functions on the unit ball
  of a Hilbert space and applications   Let $B_E$ be the open unit ball of a complex finite or infinite dimensional
Hilbert space. If $f$ belongs to the space $\mathcal{B}(B_E)$ of Bloch
functions on $B_E$, we prove that the dilation map given by $x \mapsto
(1-\|x\|^2) \mathcal{R} f(x)$ for $x \in B_E$, where $\mathcal{R} f$ denotes
the radial derivative of $f$, is Lipschitz continuous with respect to the
pseudohyperbolic distance $\rho_E$ in $B_E$, which extends to the finite and
infinite dimensional setting the result given for the classical Bloch space
$\mathcal{B}$. In order to provide this result, we will need to prove that
$\rho_E(zx,zy) \leq |z| \rho_E(x,y)$ for $x,y \in B_E$ under some conditions on
$z \in \mathbb{C}$. Lipschitz continuity of $x \mapsto (1-\|x\|^2) \mathcal{R}
f(x)$ will yield some applications which also extends classical results from
$\mathcal{B}$ to $\mathcal{B}(B_E)$. On the one hand, we supply results on
interpolating sequences for $\mathcal{B}(B_E)$: we show that it is necessary
for a sequence in $B_E$ to be separated in order to be interpolating for
$\mathcal{B}(B_E)$ and we also prove that any interpolating sequence for
$\mathcal{B}(B_E)$ can be slightly perturbed and it remains interpolating. On
the other hand, after a deep study of the automorphisms of $B_E$, we provide
necessary and suficient conditions for a composition operator on
$\mathcal{B}(B_E)$ to be bounded below.
