| Mar 1, 2018 at 13:20 | comment | added | YCor | I guess that "variety" is a mistranslation of French "variété" (which both translates in the language used on this site as "variety" and "manifold"), or from another language with the same terminology collapse, and that the OP means "projective manifold". This would be more in keeping with @BenMcKay's new answer. Anyway, the question is way too vague and the OP, at least under his/her posting name, has vanished from MO from the very minute he/she asked this question, so we won't expect any clarification. | |

| Apr 20, 2015 at 11:03 | comment | added | Ben McKay | You might look at Wilcysnki's book Projective Differential Geometry of Curves and Ruled Surfaces to get a sense of how complicated the projective invariants of curves can get. But Wilcynski is only thinking about local geometry of $C^{\infty}$ immersed curves in real projective space, so a very different story globally. | |
