SUMMARY:Algebra Seminar\, Geometry and Topology Seminar: The cohomology of hyperkahler quotients. - Thomas Nevins (UIUC)
DESCRIPTION:Abstract: Starting from a hyperkahler manifold with an action of a compact Lie group\, one can build a hyperkahler quotient as the quotient space of a certain submanifold determined by the hyperkahler structure and the group action. Many interesting manifolds can be built this way\, even starting from a group acting...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=10118

SUMMARY:Algebra Seminar: Contraction algebras and noncommutative derived geometry - Matt Booth (University of Edinburgh)
DESCRIPTION:Abstract: Given a threefold flopping contraction\, one can associate to it a finite-dimensional noncommutative algebra\, the contraction algebra\, which controls the noncommutative deformation theory of the flopping curves. If the threefold was smooth\, this algebra is conjectured to determine the complete local geometry of the base. I'll talk about a new...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=10237

SUMMARY:Algebra Seminar: Canonical lifts and delta-structures - Lance Gurney (University of Amsterdam)
DESCRIPTION:Abstract: The Serre-Tate theorem says that ordinary abelian varieties over finite fields can be "canonically" lifted to the Witt vectors of the base field. However\, both ordinariness and Witt vectors make sense over any base S where p is nilpotent. This leads to the question: can a family of ordinary abelian...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=10235

SUMMARY:Algebra Seminar: Galois theory for (derived) commutative rings - Andrew Baker (University of Glasgow )
DESCRIPTION:Abstract: Classical Galois theory of fields (as met in an undergraduate course) was generalised to commutative rings around 1960 by Auslander\, Goldman\, Chase\, Harrison and Rosenburg. Around the same time\, Grothendieck developed the theory of etale coverings of schemes and gave a more geometric view. In the ensuing half century the general...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=10223

SUMMARY:Algebra Seminar: Representation motives\, a cautionary tale - Lieven Le Bruyn (University of Antwerp)
DESCRIPTION:Abstract: Principal GL(n)-bundles (aka vector bundles) are locally trivial in the Zariski topology\, whereas principal PGL(n)-bundles (aka Azumaya algebras) are not\, to the delight of every non-commutative algebraist. Still\, this makes the calculation of motives of representation schemes of algebras next to impossible. In very special cases\, Brauer-Severi schemes (and their...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=10230

To this end we will study p-adic completions...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=10325

We have many examples\, and classification results in many dimensions. The general classification\, however\, is still widely open.
