Noncommutative versions of some classical birational transformations
In the paper 'arXiv:1410.5207' (to appear in Journal of Noncommutative Geometry) Michel Van den Bergh and I generalize some classical birational transformations to the noncommutative setting. In particular we show that 3dimensional quadratic Sklyanin algebras (noncommutative projective planes) and 3dimensional cubic Sklyanin algebras (noncommutative quadrics) have the same function field. In the same vein we construct an analogue of the Cremona transform for noncommutative projective planes. In this talk I will explain the approach and motivation for our paper. The motivation is based on the construction of the Cremona transform (in the commutative setting) using linear systems. I will also recapitulate some relevant facts about noncommutative surfaces and ArtinSchelter regular (Z)algebras.

Noncommutative resolutions of nonnoetherian singularities and the nature of time
Quantum nonlocality is the strange phenomenon where two entangled particles can affect each other instantaneously, regardless of how far apart they are. I will explain how this phenomenon can be described geometrically as a nonnoetherian singularity in spacetime. I will then introduce the notion of a noncommutative resolution of such a singularity, and describe how this notion fits into the quantum world.

Noncommutative resolutions of quotient singularities
SlidesThis is joint work with Michel Van den Bergh. We generalize standard results about noncommutative resolutions of quotient singularities for finite groups to arbitrary reductive groups. We show in particular that quotient singularities for reductive groups always have noncommutative resolutions in an appropriate sense. We discuss a number of examples, both new and old, that can be treated using our methods; twisted noncommutative crepant resolutions exist in previously unknown cases for determinantal varieties of symmetric and skewsymme tric matrices.

Lie algebroids in the LodayPirashvili category
We describe LieRinehart algebras in the tensor category of linear maps in the sense of Loday and Pirashvili and construct a functor from LieRinehart algebras (in the category of linear maps) to Leibniz algebroids.

Universal Kmatrices via quantum symmetric pairs
Slides
The construction of the universal Rmatrix for quantum groups produces solutions of the YangBaxter equation on tensor products of representations of that quantum group. This gives an action of the braid group of type A, endowing the category of finite dimensional Uq(g)representations with a structure of a braided tensor category. I will explain how the theory of quantum symmetric pairs allows an analogous construction of a universal K

Birational commutative and noncommutative geometry
In my talk I will construct a functor from some class of skew fields to some class of commutative fields with map \( Q( C[x, \partial_x]) \to Q (C[x, y]) \) as the main example. I will also provide some link between this construction and some known results and conjectures on skew fields.

Escher exhibit
While not part of the official program, attendees might be interested in the M. C. Escher exhibit at the Scottish National Gallery of Modern Art. There may be a semiorganised outing to the exhibit on Saturday afternoon.
