In physics, Lagrangian mechanics is a formulation of classical mechanics founded on the stationary-action principle (also known as the principle of least action). It was introduced by the Italian-French mathematician and astronomer Joseph-Louis Lagrange in his 1788 work, Mécanique analytique. Lagrangian mechanics describes a mechanical system as a pair consisting of a configuration … TīmeklisDe nition 1.5. A Lagrangian submanifold is Ln M2nsuch that !j L= 0. Example 1.6. In (R2n x i;y i;! 0), the space R n x i is a Lagrangian submanifold. On a surface, any simple closed curve is a Lagrangian submanifold. In T N, there is the zero section, and there are also the cotangent bers. In R2n, the product Q S1(r i) is Lagrangian.
