Differential Geometry of Surfaces,Let us consider a surface in space, given by an equation of the form . (.) = 0. We shall assume we have a map from a region of the plane, with coordinates (.) onto part of the surface, and that we can differentiate this map as often as we like. We assume that at each point of the surface the directions u-increasing and .-increasing are distinct.

,Across the Rhine — Möbius’s Algebraic Version of Projective Geometry,In 1827 Möbius published his . or ... The word “barycentre” means centre of gravity, but the book is not about mechanics but geometry. It is most concerned with, and is best remembered for, introducing a new system of coordinates, the barycentric coordinates.
