Spherical error term

WebAccording to a talk by Domingo Luna around 1985, the term spherical variety is not derived from spheres, at least not directly. Firstly, spheres are way too atypical, e.g., their compactification theory is pretty pointless. Secondly, in invariant theory circles spheres are called quadrics anyway. Webspherical. having the form of a sphere; globular. formed in or on a sphere, as a figure. of or relating to a sphere or spheres. pertaining to the heavenly bodies, or to their supposed …
