Could be, but some reducible curves pass the test: sage: Kz.<x,y,z>=GF(3)[] sage: f2=(x+y)*(x+y-1);g2=x+y+z+1 sage: C=Curve([f2,g2]) sage: C.irreducible_components() [ Closed subscheme of Affine Space of dimension 3 over Finite Field of size 3 defined by: z + 1, x + y, Closed subscheme of Affine Space of dimension 3 over Finite Field of size 3 defined by: z - 1, x + y - 1 ] sage: C.projective_closure() Projective Curve over Finite Field of size 3 defined by -x0^2 + x3^2, x0 + x1 + x2 + x3 -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
