Degenerate Time-dependent Lagrangians of Second Order: the Fourth Order Diierential Equation Problem
نویسنده
چکیده
We develop a constraint algorithm for degenerate time-dependent Lagrangians of second order and solve the so-called fourth order diierential equation problem. The study is inspired in the Gotay and Nester constraint algorithm and the notion of intermediate spaces introduced by Grr acia, Pons and Romm an-Roy.

On the Variational Characterization of Generalized Jacobi Equations
We study higher{ordervariational derivativesof a generic second{order Lagrangian L 0 = L 0 (x; ; @; @ 2) and in this context we discuss the Jacobi equation ensuing from the second variation of the action. We exhibit the diierent inte-grations by parts which may be performed to obtain the Jacobi equation and we show that there is a particular integration by parts which is invariant. We introduce...
متن کاملSecond Order Lagrangian Twist Systems: Simple Closed Characteristics
We consider a special class of Lagrangians that play a fundamental role in the theory of second order Lagrangian systems: Twist systems. This subclass of Lagrangian systems is deened via a convenient monotonicity property that such systems share. This monotonicity property (Twist property) allows a nite dimensional reduction of the variational principle for nding closed characteristics in xed e...

متن کاملOne - way Large Range Step Methods forHelmholtz
A useful approach for long range computation of the Helmholtz equation in a waveguide is to re-formulate it as the operator diierential Riccati equation for the Dirichlet-to-Neumann (DtN) map. For waveguides with slow range dependence, the piecewise range independent approximation is used to derive a second order range stepping method for this one-way re-formulation. The range marching formulas...
متن کاملOscillation Theory and Numerical Solution of Sixth Order Sturm-liouville Problems
Following earlier work on fourth order problems, we develop a shooting method to approximate the eigenvalues of 6th order Sturm-Liouville problems using a spectral function N() which counts the number of eigenvalues less than. This requires anòscillation' count obtained from certain solutions of the diierential equation, and we develop explicit algorithms for obtaining the exact oscillation cou...
