Algebra research group
Algebraic research at York covers a wide spectrum of interests, from pure group theory, representation theory and semigroup theory to applications of algebraic techniques in geometry, quantum physics and biology. The department is a fertile breeding ground for research, with regular organized seminars and study groups complemented by plenty of opportunities for informal discussion. We are also always on the lookout for strong PhD students in all areas of algebra; please see the Pure PhD projects page for some project ideas, and please also feel free to get in touch with any member of staff if you want to find out more. For details of individual members' interests, please click here.
Seminars and Study Groups
We run a weekly Algebra Study Group during term time. Please contact Michael Bate for details of the current topic, or to be included on the email list for this group.
External speakers in the area of Algebra are usually invited to give a talk in the Algebra Seminar, which is also a forum for internal research seminars. The next talk is shown below.
Date and time:
October 5, 2015, 16:15
Speaker:
Emilie Dufresne (Durham)
The study of separating invariants is a new trend in Invariant Theory and a return to its roots: invariants as a classification tool. A separating set is a set of invariants whose elements separate any pair of points that can be separated by some invariant. Such a set need not generate the ring of invariants.
