In mathematics, especially differential geometry, the cotangent bundle of a smooth manifold is the vector bundle of all the cotangent spaces at every point in the manifold. It may be described also as the dual bundle to the tangent bundle. This may be generalized to categories with more structure than smooth manifolds, such as complex manifolds, or (in the form of cotangent sheaf) algebraic varieties or schemes. In the smooth case, any Riemannian metric or symplectic form gives an isomorphism between the cotangent bundle and the tangent bundle, but they are not in general isomorphic in other categories.

  • 数学、特に微分幾何学において、滑らかな多様体の余接束 (英語: cotangent bundle) は、多様体のすべての点におけるすべての余接空間からなるベクトル束である。それはまた接束の双対束として記述することもできる。 (ja)

  • 微分几何中,流形的余切丛是流形每点的余切空间组成的向量丛。余切空间有一个标准的辛形式,从中可以一个余切丛的非退化的体积形式。因此,本身作为一个流形的余切丛总是可定向的。可以在余切丛上定义一组特殊的坐标系;这些被称为正则坐标。因为余切丛可以视为辛流形,任何余切丛上的实函数总是可以解释为一个哈密顿函数;这样余切丛可以理解为哈密顿力学讨论的相空间。 (zh)
  • En géométrie différentielle, le fibré cotangent associé à une variété différentielle M est le fibré vectoriel (en) T*M de son fibré tangent TM : en tout point m de M, l' (en) est défini comme l'espace dual de l'espace tangent : En conséquence, le fibré cotangent d'une variété différentielle peut être considéré comme l'espace des phases d'un système dynamique (dont la variété paramètre les variables de position), et l'on peut y écrire des équations d'évolution.
