Eighty-first BLOC meeting


Bristol Leicester Oxford Colloquium

The 81st BLOC meeting will be held on Friday 24th August 2018 in the Department of Mathematics, University of Leicester. Talks will take place in the Michael Atiyah Building, room 119.



12.30 Lunch: "Graduate Kitchen", First floor, Charles Wilson Building

14.00 Jenny August (Edinburgh) The Derived Equivalence Class of Contraction Algebras

15.00 Charles Eaton (Manchester) Donovan's conjecture and blocks of abelian defect groups


16.45 Karin Erdmann (Oxford) Tame symmetric algebras from surface algebras

Please let Jason Semeraro or Nicole Snashall know if you are coming to the BLOC meeting, particularly if you wish to join us for lunch.


Jenny August: In this talk, we consider a fundamental problem in homological algebra: given a finite dimensional algebra A, can we find all the algebras which are derived equivalent to A. I will explain some of the difficulties in answering this question for a general algebra before describing a class of finite dimensional algebras arising from geometry, known as contraction algebras. We show that these algebras have nice properties allowing us to bypass these difficulties and completely answer the above question.

Karin Erdmann: This is on a joint project with Andrzej Skowronski. We investigate tame symmetric algebras related to algebras constructed from surface triangulations, and which generalize naturally tame blocks of group algebras. The project divides canonically into three parts, with weighted surface algebras as the general frame.



BLOC is supported by an LMS Scheme 3 grant, which is used to help offset travel costs for participants, with priority given to covering travel and accommodation costs for speakers and postgraduates.

Travel information is HERE.

There will be time for informal discussions during the meeting.
