- Castelnuovo–de_Franchis_theorem abstract "In mathematics, the Castelnuovo–de Franchis theorem is a classical result on complex algebraic surfaces. If X is such a surface, projective and non-singular, suppose given two differentials of the first kindω1 and ω2on X which are linearly independent but with wedge product 0. Then there is a non-singular algebraic curve C, a regular morphismφ: X → C,and differentials of the first kind ω′1 and ω′2 on C such thatφ*(ω′1) = ω1 and φ*(ω′2) = ω2.This result is due to Guido Castelnuovo and Michele de Franchis (1875–1946). (The converse, that two such pullbacks would have wedge 0, is immediate.)".
