coordinate chart (plural coordinate charts)

  1. (differential geometry) A homeomorphism from a local neighborhood around a point on a topological n-manifold in a Banach space to an n-dimensional Banach space (typically a subspace of the space the manifold is embedded in).
    Synonyms: chart, coordinate map, surface patch
    • 2016 September 30, Kristopher Tapp, Differential Geometry of Curves and Surfaces (Undergraduate Texts in Mathematics)‎[1], Springer, →ISBN, →OCLC, page 125:
      A set   is called a regular surface if each of its points has a neighborhood in   that is diffeomorphic to an open set in  . That is, for every  , there exists a neighborhood,  , of   in  , an open set  , and a diffeomorphism  . Such a diffeomorphism   is called a surface patch or a coordinate chart. A collection of surface patches that together cover all of the points of   is called an atlas for  .

Usage notes

edit
  • Some authors refer to the pair of the neighborhood the mapping is defined on and the mapping together (i.e.   instead of  , where  ) as the coordinate chart while referring to the mapping alone as the coordinate map.
