Let D be the unit disk in C,
Lip (D) the space of functions, f, holomorphic in D, continuous on D and satisfying
a Lipschitz condition:
If S = {ai}x=1∞∈ D is a discrete sequence with no accumulation points in D, let
Lip (S) be the set of functions, g, defined on S satisfying
We say S is a Lip (D) interpolating (LI) sequence if the restriction mapping from
Lip (D) to Lip (S) given by f → f|S is surjective. Our aim is to describe some of the
properties of such sequences and to give some examples. Specifically we show
that an LI sequence must either be a uniformly separated sequence, or the
union of two such sequences which approach one another as they tend to
∂D.
