3. List of coordinate charts - Wikipedia

   en.wikipedia.org/wiki/List_of_coordinate_charts

   Coordinate charts are mathematical objects of topological manifolds, and they have multiple applications in theoretical and applied mathematics. When a differentiable structure and a metric are defined, greater structure exists, and this allows the definition of constructs such as integration and geodesics .

4. Surface (topology) - Wikipedia

   en.wikipedia.org/wiki/Surface_(topology)

   More generally, a (topological) surface with boundary is a Hausdorff topological space in which every point has an open neighbourhood homeomorphic to some open subset of the closure of the upper half-plane H 2 in C. These homeomorphisms are also known as (coordinate) charts. The boundary of the upper half-plane is the x-axis.

5. Boundary (topology) - Wikipedia

   en.wikipedia.org/wiki/Boundary_(topology)

   In topology and mathematics in general, the boundary of a subset S of a topological space X is the set of points in the closure of S not belonging to the interior of S. An element of the boundary of S is called a boundary point of S. The term boundary operation refers to finding or taking the boundary of a set.

6. Atlas (topology) - Wikipedia

   en.wikipedia.org/wiki/Atlas_(topology)

   A transition map provides a way of comparing two charts of an atlas. To make this comparison, we consider the composition of one chart with the inverse of the other. This composition is not well-defined unless we restrict both charts to the intersection of their domains of definition. (For example, if we have a chart of Europe and a chart of ...
