Algebroid

In mathematics, algebroid may refer to several distinct notions, which nevertheless all arise from generalising certain aspects of the theory of algebras or Lie algebras.


 * Algebroid branch, a formal power series branch of an algebraic curve
 * Algebroid cohomology
 * Algebroid multifunction
 * Courant algebroid, an object generalising Lie bialgebroids
 * Lie algebroid, the infinitesimal counterpart of Lie groupoids
 * Atiyah algebroid, a fundamental example of a Lie algebroid associated to a principal bundle
 * R-algebroid, a categorical construction associated to groupoids
