surface
A surface is a two-dimensional topological manifold. A closed surface is a surface without boundary.
A result called the “classification theorem” gives us a symbolic semantics, matching the geometrical view point, in terms of genera, orientability and number of boundary components. Together with the connected sum operation, they make available a powerful language to be explored and exploited.
As an example of a surface take the two torus, the boundary of a solid sugar donut shaped cake , where is the familiar modulus one complex numbers.
