WebIn mathematics, a surface is a two-dimensional manifold. Some surfaces arise as the boundaries of three-dimensional solids; for example, the sphere is the boundary of the solid ball. Other surfaces arise as graphs of functions of two variables; see the figure at right. However, surfaces can also be defined abstractly, without reference to any ... WebThe more typical definition is that a manifold is a space that is locally like R n. I dislike it philosophically, but it's easier to formalize than M1-M3 above. To formalize it, you can …
