On the contingency of predicativism.

Franz Luef (NTNU) will give  a talk with title "Sigma-models solitons on noncommutative spaces"

Abstract: Results from time-frequency analysis and Gabor analysis allow the construction of new classes of sigma-model solitons over the Moyal plane and over noncommutative tori, taken as source spaces, with a target space made of two points. A natural action functional leads to self-duality equations for projections in the source algebra. Solutions, having non-trivial topological content, are constructed via suitable Morita duality bimodules. This is joint work with L. Dabrowski and G. Landi.

Benjamin Racine, Postdoctoral Fellow , ITA

Bartosz K. Kwaśniewski (University of Southern Denmark, Odense) will talk on: Topological aperiodicity for product systems of C*-correspondences

Abstract:We introduce a semigroup of multivalued maps dual to a product system of $C^*$-correspondences over an Ore semigroup. Under a certain aperiodicity condition on the dual semigroup we obtain a uniqueness theorem and a simplicity criterion for the associated Cuntz-Pimsner algebra. These results generalize similar statements for crossed products by groups (R. J. Archbold, J. S. Spielberg) and Exel’s crossed products (R. Exel, A. Vershik). They also give interesting conditions for topological higher rank graphs, and apply to the new Cuntz $C^*$-algebra $\mathcal{Q}_\mathbb{N}$ arising from the `$ax+b$'-semigroup over natural numbers. (Based on joint work with Wojciech Szymański.)

Friday seminar by Philipp Mitteröcker from Universität Wien

Geir Ellingsrud, UiO, gives the Seminar in Algebra and Algebraic Geometry:

Modular curves I

Adam P.W. Sørensen will talk on Nuclear dimension of UCT Kirchberg algebras

Abstract: Nuclear Dimension is a regularity property for C*-algebras that is based on the type of properties currently being taught in Topics in Operator Algebras. We will go over the definition and motivation and discuss known results.
