- Let C be an algebraic curve in n dimensional space over an algebraically
- closed field. Let x be a point of C. We can describe a tangent to C
- at x as a line going through x and a point of C infinitely near to x,
- hence through 2 consecutive points of C. If the line actually goes through
- 3 consecutive points of C, we call it a point of inflection. I think that
- if the line goes through 4 consecutive points, it is called a hyperflex,
- but I don't have a reference for this terminology.
-
- Can someone confirm or deny this and provide a reference?
