This, of course, depends on what’s meant by ‘algebraic geometry’, and one finds strangely varying descriptions, from one author to another: At its heart, algebraic geometry is nothing more than a dictionary. Therefore. using the chord-tangent composition law notation. and are both inﬂection points.

Whitehead -- The Jacobi identity for Whitehead products / by Hiroshi Uehara and W. Thus is a point of inﬂection of V( ) if and only if 3 divides (, 0, ) = 2 −2 + higher order terms. These objects can be classified quickly by looking at global properties such as how many holes, described by the genus, how much curvature they have, described by the euclidean characteristic, how many vector zeros on the surfaces, described by how many bald spots would appear if hair sprouted on the surface and someone wanted to comb it and how many times the surface wraps around the interior, described by its degree.
