Gregor Schaumann (MPI Bonn): Algebraic operations from topological field theory

Abstract: Topological field theories provide strong connections between algebra and topology. The aim of this talk is to summarize some recent developments along theses lines. In the case of 3-dimensional TFTs, diagrammatic representations allow one to get intuition for higher categorical traces, symmetrized products and center constructions.
This is joint work with Christoph Schweigert und Jürgen Fuchs.
