Query: A Julia-Wolff-Carath\'eodory theorem for infinitesimal generators in the
  unit ball   We prove a Julia-Wolff-Carath\'edory theorem on angular derivatives of
infinitesimal generators of one-parameter semigroups of holomorphic self-maps
of the unit ball $B^n\subset\mathbb{C}^n$, starting from results recently
obtained by Bracci and Shoikhet.
