- Course objectives
- As a basic undelying geometrical structures of variational theories fibered manifolds are considered. For mechanics the base of a fibered manifold is one-dimensional, for field theories it is m-dimensional (m>1). The presentation of fundamental concepts and theorems concerning the geometry of fibered manifolds, differential forms on fibered manifolds, formulation of variational problems and proofs of basic formulas of variational theories allows students to obtain a basic knowledge of correct approaches to mathematical problems of variational theories. The presentation includes also problems of variational sequences and their meaning for understanding such aspects of theories as the variationality of equations of motion and the trivial variational problem.
Absolving the discipline students obtain following abilities and skills:
* Understanding of fundamental problems of calculus of variations on fibered manifolds and the connection of the general mathematical theory with physical variational theories.
* Skill of the practical calculus of jets, fibered manifolds and their jet prolongations, fibered charts, associated charts, etc.
* Skills of the practical calculus of vector fields, their prolongations, calculus of differential forms on fibered manifolds.
* Skill of practical formulation of variational problems, especially those with physical meaning, derivation of equations of motion.
* Practical use of the variational sequence for solving problems o variational triviality of a lagrangian or problems of variationality of equations of motion.
