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.
