Chisini's conjecture on generic coverings of the projective plane
Chisini's conjecture on generic coverings of the projective plane
Let be a cuspidal branch curve, and let
be generic coverings of degree at least , meaning that their branch curve has only nodes and cusps and the local monodromy at a smooth point of the branch curve is a transposition. Two such coverings are equivalent when they are equivalent as coverings of .
Chisini's conjecture. Given two generic coverings and , both of degree at least , with the same branch curve , the coverings and are equivalent.
The conjecture asks whether a generic covering of degree at least is determined by its branch curve. The supplied text gives no resolution or qualification of its status.
