SUMMARY:Algebra Seminar: Algebraic K-theory of singularity categories of quotient singularities - Evgeny Shinder (University of Sheffield)
DESCRIPTION:Abstract: In this joint work in progress with Nebojsa Pavic\, we study Schlichting K-groups of the Buchweitz-Orlov singularity category. After developing the basic techniques\, we concentrate on the case of isolated quotient singularities\, where we prove that K_0 of the singularity category is finite torsion and that its K_1 is zero....\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=10149

DESCRIPTION:Abstract: I will describe Givental's quantisation formalism\, a powerful language for working with Gromov-Witten invariants\, and explain how it is related to a Floer-theoretic version of S^1-equivariant Tate cohomology of loop space. (This connection was first observed by Morava.) I will then describe recent work by Nabijou\, building on older work...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=10320

SUMMARY:Algebra Seminar: Dimer models and Hochschild cohomology - Michael Wong (University College London)
DESCRIPTION:Abstract: A dimer model is a type of quiver embedded in a Riemann surface. It gives rise to an associative\, generally noncommutative algebra called the Jacobi algebra. In the version of mirror symmetry proved by R. Bocklandt\, the wrapped Fukaya category of a punctured surface is equivalent to the category of...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=10332
