Lagrangian system
TīmeklisWhat is a Lagrangian system? The BF model Lagrangian, short for “Background Field”, describes a system with trivial dynamics, when written on a flat spacetime … 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 …
