Book 2004ent variables leads to the general conservation laws of Emmy Noether, an important tool in exploiting symmetries. Other parts of this volume deal with Legendre-Jacobi theory and with field theories. In particular we give a detailed presentation of one-dimensional field theory for nonpara metric and

Huajin Tang,Kay Chen Tan,Zhang Yiity conditions will be particularly useful for the calculus of variations; these are the so-called .. A particular feature of every such field is that it defines a scalar function . whose level surfaces form a one-parameter family of hypersurfaces which are transversal to all field curves. This func

Weierstrass Field Theory for One-Dimensional Integrals and Strong Minimizersgiven extremal . of a variational integral . is, in fact, a .. This will be achieved by a method the elements of which were developed by Weierstrass. One of its basic ideas is to consider a whole bundle of extremals instead of a single one, just as one investigates in optics . instead of isolated si
