Sam Sanders, Ghent and Munich, will give a lecture with the tittle
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.
