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.

Morita equivalence classes of blocks


Series: 
Algebra Seminar
Date and time: 
October 27, 2014, 16:15
Speaker: 
Charles Eaton (Manchester)
Room: 
G/109

 I will talk about the problem of determining the Morita equivalence classes of blocks of finite groups with a given defect group. The fundamental conjecture in this area is Donovan's, that there are only finitely many Morita equivalence classes of blocks with a given defect group. A positive or negative conclusion to the conjecture would profoundly influence the way we regard representations of finite groups.

The York Semigroup meets every week in term time and is a mixture of informal sessions, led by York Semigroup PhD students, and more formal presentations.
