Lie Bracket of Vector Fields

In the mathematical field of differential topology, the Lie bracket of vector fields, Jacobi–Lie bracket, or commutator of vector fields is a bilinear differential operator which assigns, to any two vector fields X and Y on a smooth manifold M, a third vector field denoted . It is the specialization of the Lie derivative to the case of Lie differentiation of a vector field. Indeed, equals the Lie derivative .

It plays an important role in differential geometry and differential topology, and is also fundamental in the geometric theory for nonlinear control systems (Isaiah 2009, pp. 20–21, nonholonomic systems; Khalil 2002, pp. 523–530, feedback linearization).

A generalization of the Lie bracket (to vector-valued differential forms) is the Frölicher–Nijenhuis bracket.

Famous quotes containing the words fields and/or lie:

    The need to exert power, when thwarted in the open fields of life, is the more likely to assert itself in trifles.
    Charles Horton Cooley (1864–1929)

    The lakes are something which you are unprepared for; they lie up so high, exposed to the light, and the forest is diminished to a fine fringe on their edges, with here and there a blue mountain, like amethyst jewels set around some jewel of the first water,—so anterior, so superior, to all the changes that are to take place on their shores, even now civil and refined, and fair as they can ever be.
    Henry David Thoreau (1817–1862)
