Real space quadrics and μ-bases
In Euclidean 3-space, a quadric surface is the zero set of a quadratic equation in three variables. Its projective closure can be given as the closure of the image of a rational parametrization P:R2→R4 where P maps the parameters (s,t)∈R2 to the tuple (a,b,c,d)∈R4 and a, b, c, d are linearly indepen...
