Space Curve

释义

Space Curve

A curve which may pass through any region of 3-D space, as contrasted to a Plane Curve which must lie ina single Plane. Von Staudt (1847) classified space curves geometrically by considering the curve

(1)

and assuming that the parametric functions

for

, 2, 3 are given by Power Series whichconverge for small

. If the curve is contained in no Plane for small

, then a coordinate transformation puts theparametric equations in the normal form

			(2)
			(3)
			(4)

for integers

, called the local numerical invariants.
