Dynamical Stability in Lagrangian Systemsper presents original results on autonomous Lagrangian systems on the two torus including a precise description of Mather’s beta function. Examples are given of mechanical systems with non-strictly convex beta function and with an Euler-Lagrange minimizer which is not a Jacobi minimizer.

The Method of Rational Approximations: Theory and Applicationslactic dynamics. Applications of the method in dynamical systems of physical, chemical or biological importance, are under consideration. The results show that we can use this method easily, in cases where we do not know the form of the solution, and simultaneously we have very good accuracy for the first and second order terms.

If we consider the various possible choices of .0, for a given .0, then changes to.∞ (.0,R), ≅ 0 (i.e., the paramctrisation of the orbits). Rcparametrisation does not change the periodic orbits but usually does change the periods.
