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

The Standard Model Effective Theory and Dimension 6 Operators
Speaker:Prof. Aneesh V. Manohar (University of California, San Diego)
Abstract:3. Vorlesung im Rahmen der Schrödinger-Gastprofessur: Effective theory methods are applied to the standard model to study the effects of new physics in a model independent way. The talk outlines some recent results on the renormalization of dimension 6 operators, and the implications for processes such as Higgs decay

Solutions of the conformal constraint equations with non-constant mean curvature
Speaker:Romain Gicquaud (Tours)
Abstract:im Rahmen des Literaturseminars für Gravitation: Constructing broad classes of (physically relevant) initial data for the Cauchy problem is an important issue in general relativity. From the Gauss and Codazzi equations, the 0th order initial data (the metric induced on a Cauchy surface) and the first order initial data (the second fundamental form of the Cauchy surface) cannot be chosen arbitrarily: they have to satisfy some constraint equations. One of the main methods for studying these equations is the conformal method which was highly successful for constructing and classifying constant mean curvature(CMC) initial data. However, constructing non CMC initial data remains a widely open subject. In this talk I will describe recent results on the construction of solutions to the constraint equations with non constant mean curvature by the conformal method.

Strongly coupled phases of N = 1 S-duality
Speaker:Inaki Garcia-Etxebarria (MPI Munich)
Abstract:We have recently argued for the existence of a natural generalization of 4d N=4 SL(2,Z) duality, which applies to a vast class of N=1 theories arising from branes at singularities. I will review the motivation and evidence for the proposal, and then discuss some recent developments which indicate that intrinsically strongly coupled field theories play a fundamental role in the duality behavior of these N=1 theories.
