Teaching language

Suitable for English-speaking students

Objectives

To master classical formalisms of analytical mechanics and its application to problems of classical mechanics. In this line the student is exposed to the notions of symmetry and algebrization in the description of movement, as an introductory path to the concepts to be developed in chairs on Quantum Mechanics.

Learning outcomes and competences

This course develops skills to solve more advanced problems in more complex mechanical systems, using more sophisticated mathematical techniques.

In addition, the student will learn several concepts that play an important role in modern theoretical physics, including the principles of symmetry and the geometric structure of mechanics.

Upon completion of the course the student should be able to use the formalisms of Lagrange and Hamilton in specific examples, solve a greater variety of problems using methods of Analytical Mechanics, and apply the mathematical tools that were developed during the course.
