2. Worldsheet - Wikipedia

   en.wikipedia.org/wiki/Worldsheet

   A world-sheet is then an embedded surface, that is, an embedded 2-manifold , such that the induced metric has signature (, +) everywhere. Consequently it is possible to locally define coordinates ( τ , σ ) {\displaystyle (\tau ,\sigma )} where τ {\displaystyle \tau } is time-like while σ {\displaystyle \sigma } is space-like .

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 .

5. Mathematical diagram - Wikipedia

   en.wikipedia.org/wiki/Mathematical_diagram

   A Voronoi diagram is a special kind of decomposition of a metric space determined by distances to a specified discrete set of objects in the space, e.g., by a discrete set of points. This diagram is named after Georgy Voronoi , also called a Voronoi tessellation , a Voronoi decomposition, or a Dirichlet tessellation after Peter Gustav Lejeune ...

   The Mandelbrot set, one of the most famous examples of mathematical visualization.. Mathematical phenomena can be understood and explored via visualization.Classically, this consisted of two-dimensional drawings or building three-dimensional models (particularly plaster models in the 19th and early 20th century).
