In mathematics , the inverse problem for Lagrangianmechanics is the problem of determining whether a given system of ordinary differential equation s can arise as the Euler&ndash Lagrange equation s for some Lagrangian function. There has been a great deal of activity in the study of this problem since the early 20th century. A notable advance in this field was a 1941 paper by the United States American mathematician Jesse Douglas , in which he provided necessary and sufficient conditions for the problem to have a solution these conditions are now known as the Helmholtz conditions , after the Germany German physicist Hermann von Helmholtz .

The term Lagrangian refers to any of several mathematical concepts developed by Joseph Louis Lagrange Mathematical sciences In optimization theory, the Lagrangian function is used to solve constrained minimization problems see Lagrange multipliers . The method of approximating a difficult constrained problem with an easier problem having an enlarged feasible set allowing but penalizing some violation of constraints , is called Lagrangian relaxation . The problem of maximizing the value of the Lagrangian function, in terms of the Lagrange multiplier variable, is the Lagrangian dual problem . In the calculus of variations, the Lagrangian is a functional whose extrema are to be determined see Calculus of variations .

In mathematics , the Lagrangian Grassmannian is the smooth manifold of Lagrangian subspace s of a real symplectic vector space V . Its dimension is n n 1 2 where the dimension of V is 2n . It may be identified with the homogeneous space U n O n where U n is the unitary group and O n the orthogonal group . Following Vladimir Arnold it is denoted by n . A complex Lagrangian Grassmannian is the homogeneous space complex homogeneous manifold of Lagrangian subspace s of a complex symplectic vector space V of dimension 2 n . It may be identified with the homogeneous space of complex dimension n n 1 2 Sp n U n where Sp n is the symplectic group complex symplectic group . Topology The stable topology of the Lagrangian Grassmannian and complex Lagrangian Grassmannian is completely understood, as these spaces appear in the Bott periodicity theorem math Omega Sp U simeq U O math , and math Omega U O simeq Z times BO math they are thus exactly the Orthogonal group Homotopy groups homotopy groups of the stable orthogonal group , up to a shift in indexing dimension .

In the field of mathematical optimization , Lagrangian relaxation is a relaxation approximation relaxation method which approximation theory approximates a difficult problem of constrained optimization by a simpler problem. A solution to the relaxed problem is an approximate solution to the original problem, and provides useful information. The method penalizes violations of inequality constraint s using a Lagrangian multiplier , which imposes a cost on violations. When the Lagrangian multiplier is nonnegative and nonzero, some inequality constraint can be violated. In practice, the Lagrangian relaxed problem can be solved more easily than the original problem. The problem of maximizing the Lagrangian function of the dual variables the Lagrangian multipliers is the Lagrangian dual problem .

The Semi Lagrangian scheme SLS is a numerical method that is widely used in Numerical Weather Prediction models for the integration of the equations governing atmospheric motion. A Lagrangian description of a system such as the atmosphere focuses on following individual air parcels along their trajectories as opposed to the Eulerian description, which considers the range of change of system variables fixed at a particular point in space. Some background The Lagrangian rate of change of a quantity math F math is given by math frac DF Dt frac partial F partial t mathbf v cdot vec nabla F, math where math F math can be a scalar or vector field and math mathbf v math is the velocity field. The first term on the right hand side of the above equation is the local or Eulerian rate of change of math F math and the second term is often called the advection term .
