Course manual 2019/2020

Course content

The course starts by introducing the basic notion of a group, its generators and relations. Important concepts such as cosets, conjugacy classes, and (normal) subgroups will be explained. After briefly describing examples like the cyclic, dihedral, and Platonic groups, a more detailed discussion will be given of the permutation group S_N of N elements. Continuous groups are first introduced with the example of the two and three-dimensional rotation groups SO(2) and SO(3), but quickly extended to the classical groups, with a extensive discussion of SU(N). The theory of Lie algebras is explained, including a discussion of the Cartan-Weyl basis and the root lattice. The Cartan classification and the existence of exceptional groups is briefly discussed. A significant part of the course covers the representations of groups through matrices, which includes the use of the characters for finite groups, Young tableaux for SU(N) and the (general) construction of the unitary highest weight representations. The Lorentz group will also be discussed.

Objectives

Understand, apply and evaluate basic concepts: group axioms, cyclic, dihedral and permutation group, platonic solids, conjugacy, subgroups, cosets, homomorphism

Attendance

Requirements concerning attendance (OER-B).

In addition to, or instead of, classes in the form of lectures, the elements of the master’s examination programme often include a practical component as defined in article 1.2 of part A. The course catalogue contains information on the types of classes in each part of the programme. Attendance during practical components is mandatory.

Assessment

You are not allowed to bring any literature, notes, calculators etc. to any of the exams. The retake is for the whole course.

Inspection of assessed work

After the grades of the exams are posted on canvas, we will schedule a time for students to inspect their work. The exam questions and solutions will be posted on canvas.

Fraud and plagiarism

The 'Regulations governing fraud and plagiarism for UvA students' applies to this course. This will be monitored carefully. Upon suspicion of fraud or plagiarism the Examinations Board of the programme will be informed. For the 'Regulations governing fraud and plagiarism for UvA students' see: www.student.uva.nl
