Differential geometry (DG) applications[edit | edit source]

  • In physics both Electromagnetism and general relativity (GR) employ extensively DG concepts and tools; our Universe was represented in Einstein's GR as a smooth manifold equipped with a pseudo-Riemannian metric, that describes the curvature of space-time; however, refined GR models of space-times in the inflationary universe regard the space-times as a directed sequence of space-times or a limit .
  • Symplectic manifolds are especially useful to the study of Hamiltonian systems.
  • In engineering there are numerous applications of differential geometry in digital signal processing, architectural design, image enhancement, and so on.
  • The Fisher information metric is used in information theory and advanced statistics.
  • computer graphics and CAD computer-aided design are based on differential geometry.
  • In Geophysics, differential geometry is routinely used to analyze and describe geologic structures, as well as several other applications

Often differential geometry is considered to be one of the more applied areas of mathematics.
