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.

On graded decomposition numbers for Cherednik algebras


Series: 
Algebra Seminar
Date and time: 
April 27, 2015, 16:15
Speaker: 
Chris Bowman (City University)
Room: 
G/109
Given a complex reflection group of type G(l,1,n), we wish to understand the representation theory of the associated Hecke algebra (a certain q-deformation of this group).  Rouquier  has shown that the Cherednik algebras control the representation theory of these Hecke algebras in much the same way as the general linear group controls the representation theory of the symmetric group.
