P.<x,y,z> = ProjectiveSpace(GF(3),2)
C = Curve(x^2)
C.is_irreducible()
C.irreducible_components()
Does that make any sense?Tue, 21 Mar 2017 19:55:37 +0100https://ask.sagemath.org/question/37025/the-curve-c-x2-0-has-only-one-irreducible-component-but-sage-says-that-it-is-reducible/Comment by kcrisman for <p>The curve below has only one irreducible component, but sage says that it is reducible:</p>
