http://www.encyclopediaofmath.org/index.php/Differential_geometry Differential geometry - Encyclopedia of Mathematics A branch of geometry dealing with geometrical forms, mainly with curves and surfaces, by methods of mathematical analysis. In differential geometry the properties of curves and surfaces are usually studied on a small scale, i.e. the study concerns properties of sufficiently small pieces of them.
