Keywords: Conjugate points, calculus of variations, second variation MSC Classification: 49K15 Abbreviated Title: Conjugate Points Revisited 1 Introduction The calculus of variations is concerned with optimization problems in infinite dimensions, in which the domain is a set of functions rather than Rn. The classic problem is to minimize a

The maxima and minima of a function may be located by finding the points where its derivative vanishes (i.e., is equal to zero). The extrema of functionals may ...

The Calculus of Variations is concerned with solving Extremal Problems for a Func- tional. That is to say Maximum and Minimum problems for functions whose domain con- tains functions,Y(x) (orY(x1;¢¢¢x2), orn-tuples of functions). The range of the …

Oct 29, 2014 · Let us re-examine the classical conditions of Calculus of Variations geared to obtain a strong minimum (in the topology of the uniform convergence) for an arbitrary Lagrangian function L (t,q,\dot {q}), convex in the velocities \dot {q}. The result can be obtained in the geometric setup of symplectic geometry using the Hamiltonian description of the problem: the joint use of the theory of Poincaré-Cartan Integral Invariant and Young Inequality rapidly leads to the thesis.
