 One of the motivating examples for the investigation of the Hilbert scheme in general was the Fano scheme of a projective scheme.Given a subscheme formula_62 of degree formula_63 there is a scheme formula_64 in formula_65 parameterizing formula_66 where formula_18 is a formula_68-plane in formula_2, meaning it is a degree one embedding of formula_70.For smooth surfaces in formula_71 of degree formula_72, the non-empty Fano schemes formula_64 are smooth an zero dimensional.
