Seminars

We run a weekly Algebraic Geometry and Mathematical Physics Seminar - details below.

On Wednesday at 2pm there is the Pure maths Colloquium, and on Monday at 3pm we organise a learning seminar on K3 surfaces (calendar, notes, Huybrechts's book).
Talks are usually in room J11.

In November 2019, 13th-14th, we host a two-days GLEN workshop.

For a complete list of seminars hosted at the School of Maths and Stats, look at This week's seminars and This semester's seminars.

Seminars 2019/20

Francesco Sala (IPMU Tokyo)
Categorification of 2d cohomological Hall algebras

Tuesday 17th Sep, 14:00, J11

Abstract: Let M denote the moduli stack of either coherent sheaves on a smooth projective surface or Higgs sheaves on a smooth projective... Read more

Paul Johnson (Sheffield)
Partitions and Hilbert schemes of points

Tuesday 1st Oct, 12:00, J11

Abstract: This will be a gentle, expository talk explaining some connections between the two objects in the title. I will begin with... Read more

Dhruv Ranganathan (Cambridge)
A Mayer-Vietoris theorem for Gromov-Witten theory

Tuesday 8th Oct, 12:00, J11

Abstract: The Gromov-Witten theory of a smooth variety X is a collection of invariants, extracted from the topology of the space of ... Read more

Jenny August (MPIM Bonn)
The Stability Manifold of a Contraction Algebra

Tuesday 15th Oct, 12:00, J11

Abstract: For a finite dimensional algebra, Bridgeland stability conditions can be viewed as a continuous generalisation of tilting theory, providing... Read more

Pierrick Bousseau (ETH)
Quasimodular forms from Betti numbers

Thursday 17th Oct, 15:00, J11 (note unusual day)

Abstract: I will explain how to construct quasimodular forms starting from Betti numbers of moduli spaces of dimension 1 coherent sheaves on P2. This gives a proof of some stringy predictions about the refined topological string theory of local P2 in the Nekrasov-Shatashvili limit. Partly based on work in progress with Honglu Fan, Shuai Guo, and Longting Wu.

Nick Sheridan (Edinburgh)
The Gamma and SYZ conjectures: a tropical approach to periods

Tuesday 22nd Oct, 12:00, J11

Abstract: I'll start by explaining a new method of computing asymptotics of period integrals using tropical geometry, via some... Read more

Noah Arbesfeld (Imperial College London)
K-theoretic Donaldson-Thomas theory and the Hilbert scheme of points on a surface

Tuesday 29th Oct, 12:00, J11

Abstract: Tautological bundles on Hilbert schemes of points often enter into enumerative and physical computations. I'll explain how to use the Donaldson-Thomas theory of ... Read more

Ben Davison (Edinburgh)
Strong positivity for quantum cluster algebras

Tuesday 5th Nov, 12:00, J11

Abstract: I will discuss the positivity for quantum theta functions, a result of joint work with Travis Mandel. For... Read more

Gwyn Bellamy (Glasgow)
Resolutions of symplectic quotient singularities

Tuesday 19th Nov, 12:00, J11

Abstract: In this talk I will explain how one can explicitly construct all crepant resolutions of the symplectic quotient... Read more

Soheyla Feyzbakhsh (Imperial College London)

Thursday 21st Nov, 12:00, J11 (note unusual day)

Dimitri Wyss (École Polytechnique Fédérale de Lausanne)

Tuesday 3rd Dec, 12:00, J11

Sira Gratz (Glasgow)

Tuesday 10th Dec, 12:00, J11
