Abstract
We study infinite intersections of open subschemes and the corresponding intersection of Hilbert schemes. If is the collection of open subschemes of a variety containing a fixed point , then we show that the Hilbert functor of flat and finite families on the spectrum of the local ring of is given by the intersection of , where is the Hilbert functor of flat and finite families on . In particular we show that the Hilbert functor of flat and finite families on the spectrum of the local ring of is representable by a scheme.
