**Faculty of Science**

Autumn 2007

**Extent and Intensity**- 2/1. 2 credit(s) (plus extra credits for completion). Type of Completion: k (colloquium).
**Teacher(s)**- prof. RNDr. Jana Musilová, CSc. (lecturer)

Department of Theoretical Physics and Astrophysics - Physics Section - Faculty of Science

Contact Person: prof. RNDr. Jana Musilová, CSc. **Prerequisites**- differential and integral calculus of functions of one and many variables, fundamental problems of multilinear algebra (tensor calculus), differential forms on euclidean spaces
**Course Enrolment Limitations**- The course is offered to students of any study field.
**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.
**Syllabus**- 1. Fundaments of the jet theory. 2. Fibered manifolds and their jet prolongations, sections on fibered manifolds. 3. Vector fields and differential forms of fibered manifolds and on their prolongations. 4. Horizontal and contact forms. 5. Basic operations with differential forms. 6. Lagrangian, variational integral and variational formulas. 7. Equations of motion, Euler-Lagrange form. 8. Variational sequences on fibered manifolds. 9. Representations of variational sequences, Euler-Lagrange and Helmholtz-Sonin mappings. 10. Lepage forms, Lepage equivalents. 11. Trivial variational problem. 12. Variationality of equations of motion. 13. Aplications, examples, mechanics.
