A semester course for professionals
Do you work with objects such as numbers, polynomials or lattices in your programming tasks? And do you already have some background in theoretical algebra, but want to learn more about algorithms for these objects and how they can be applied in various contexts?
Algorithms in Algebra is an introductory semester course in computer algebra. You will explore how abstract algebra can be translated into practical algorithms, such as efficiently factoring polynomials, computing with abelian groups, working with lattices, and solving systems of polynomial equations. The course bridges theory and application, and is relevant for those interested in algebraic number theory, algebraic geometry, cryptography or computational mathematics.
Weekly lecture/seminar untill 12 December: Lecture: 13:15 - 15:00 hrs Seminar: 11:00 - 12:45 hrs
The course workload is expressed in ECs (European Credits), with 1 EC equalling 28 hours of study. The fee is €163 per EC. This includes lectures, tutorials, exams and one resit (if needed). Study materials are not included. Cancellation is possible up to two weeks before the course starts, with a full refund of the course fee. After that point, refunds are no longer possible, even in cases of force majeure, illness, or other circumstances.
Each of the three courses offered is worth 6 ECs.
- Registration is open until 15 August 2025.
- After submitting your registration form, you will receive an invoice.
- Once we have received your payment, you will receive a confirmation.
- A student account and student number will then be requested. Without a student number, you cannot be enrolled in a course and are not entitled to participate.
- Contract students will be registered for lectures and/or tutorials, the exam, and the resit.
Each course includes one main exam (or multiple partial exams) and one resit per academic year. If you do not pass the exam on the first attempt, you are allowed to take the resit within the same academic year.
