The aim of the course is to present the basic theory for, and applications of, the calculus of variations, i.e., optimization problems for "functions of functions". A classical example is the isoperimetric problem, to find which closed curve of a given length encloses maximal area. Many physical laws can be formulated as variational principles, i.e. the law of refraction. The calculus of variations is also a corner stone in classical mechanics, and has many other technological applications e.g. in systems theory and optimal control.

Variational problems without and with constraints. Euler's equations without and with constraints. Legendre's, Jacobi's and Weierstrass' necessary conditions for a local minimum.

Hilbert's invariant integral and Weierstrass' sufficient conditions for a strong local minimum.

Hamilton's principle and Hamilton's equations. Lagrange's och Mayer's problems.

be able to explain the basic parts of the theory in the context of an oral examination.

be able to demonstrate an ability to identify problems which can be modelled with the concepts introduced.

be able to integrate methods and views from the different parts of the course in order to solve problems and answer questions within the framework of the course.

in writing and orally, with clear logic and proper terminology be able to explain the solution to a mathematical problem within the course.
