Summary  This course provides an introduction to Lie groups (the general object responsible for smooth symmetries) and Lie algebras (their infinitesimal counterpart). A particular focus will be on compact Lie groups, including a discussion of their structure theory and classification. 
Course description 
The concept of symmetry is omnipresent in modern mathematics. Lie groups are the abstract generators of continuous symmetries, which arise in many contexts in geometry and physics. Important examples are provided by matrix groups, but the subject is strictly larger. Lie groups also always have Lie algebras associated with them, which encode infinitesimal symmetries. This course begins with a broad introduction to Lie groups and Lie algebras, starting from classical matrix groups. It then focuses on compact Lie groups, discussing their structure and ending with a classification.
The course will cover:
Matrix groups, Matrix Lie algebras. Matrix exponentiation and BakerCampbellHausdorff formula.
SU(2) and SO (3)
Lie groups and associated Lie algebras. Adjoint actions. Lie subgroups and subalgebras. Coverings & quotients. Spin groups.
Semisimple Lie algebras.
Compact Lie groups and their complexification.
Maximal tori, roots, weight lattices. Center & fundamental group.
Haar measure for (compact) Lie group. Killing form.
Weyl groups.
Cartan matrix & Dynkin diagram.
Classification of Dynkin diagrams, classification of semisimple complex Lie algebras and compact connected Lie groups.
