Nodal singular locus conjecture for projected complete intersection curves
Nodal singular locus conjecture for projected complete intersection curves
Let be a finite set of full dimension containing and satisfying Assumption. For generic polynomials , let
be the complete intersection curve, and let
be the projection forgetting the first coordinates. Nodal singular locus conjecture. The image is an algebraic plane curve with punctured points, and its singular locus consists only of nodes. This predicts that generic projected complete intersection curves have no singularities beyond ordinary double points, a property relevant to understanding the geometry and combinatorics of their plane projections; the conjecture is stated here as a further discussion and no resolution is supplied in the source.
