Oka properties of groups of holomorphic and algebraic automorphisms of   complex affine space
  We show that the group of all holomorphic automorphisms of complex affine space $\mathbb C^n$, $n>1$, and several of its subgroups satisfy the parametric Oka property with approximation and with interpolation on discrete sets.
