Equivariant Brauer groups and Galois deformations 2.
Abstract
We study the Brauer group of some concrete monoidal categories, with emphasis on the equivariant Brauer group of a triangular pointed Hopf algebra, the Brauer group of differential graded algebras, and the Brauer group of a coquasitriangular dual pointed Hopf algebra. We will study the groupoid of biGalois objects over a Hopf algebra. We will introduce a categorical version of the Clifford functor and the Brauer-Wall group.Researcher(s)

Deformations and cohomology in non-commutative derived geometry.
Abstract
My research project is at the crossroads of non-commutative geometry (in the sense of Kontsevich, Van den Bergh, . . . ) and homotopical derived geometry (in the sense of Toën, . . . ). An important inspiration is the fact [6] that a smooth proper scheme is equivalent in the derived sense to a differential graded (dg) algebra [28], and smoothness and properness boil down to properties of this dg algebra. Hence, dg algebras become models of "noncommutative schemes" [37], [60]. This approach has proven useful in topics ranging from deformation quantization to homological mirror symmetry. In this spirit, we study dg algebras [28], their twins, A1-algebras [27], stacks, and in particular deformations and Hochschild cohomology of these objects.Researcher(s)

Modular forms in non-commutatieve geometry.
Abstract
During the previous years the candidate has studied Clifford algebra valued modular forms on arithmetic subgroups of the orthogonal group O(1,n) and that are annihilated by Dirac type operators. The aim of this project is to apply and to extend these techniques to generalizations of Clifford algebras. This shall give further insight in the study of discrete quantum groups and Hopf algebras in the framework of non-commutative geometry.Researcher(s)

European Priority Programme : 'Noncommutative Geometry'.
Abstract
Recent interactions between physics and noncommutative algebra gave rise to the creation of a new area in mathematics : 'Noncommutative Geometry'. The European Science Foundation selected this for a European Priority Programme that was funded by 12 member countries. The NOG-programme is involved in the organization of congresses, workshops and summerschools and also provides fellowships and travel grants for research cooperation.
