Thin set
From Encyclopedia of Mathematics
A subset $ A $
of a domain $ D \subset \mathbf C ^ {k} $
such that, for each point $ z \in D $,
there exists an open polydisc $ \Delta ( z, r) \subset D $
and a function $ f $
which is holomorphic, not identically equal to zero, but which vanishes on $ A \cap \Delta ( z, r) $.
Comments
Usually, being thin means being a subset of an analytic set. Cf. also Thinness of a set.
