The homogeneity conjecture for supergravity backgrounds
José Miguel Figueroa-O'Farrill
These notes record three lectures given at the workshop "Higher symmetries in Physics", held at the Universidad Complutense de Madrid in November 2008. In them we explain how to co…
Supersymmetric Quantum Mechanics of Magnetic Monopoles: A Case Study
Erik Jan de Vries, Bernd J. Schroers
We study, in detail, the supersymmetric quantum mechanics of charge-(1,1) monopoles in N=2 supersymmetric Yang-Mills-Higgs theory with gauge group SU(3) spontaneously broken to U(1…
Duality covariant quantum field theory on noncommutative Minkowski space
Andre Fischer, Richard J. Szabo
We prove that a scalar quantum field theory defined on noncommutative Minkowski spacetime with noncommuting momentum coordinates is covariant with respect to the UV/IR duality whic…
On the maximal superalgebras of supersymmetric backgrounds
José Figueroa-O'Farrill, Emily Hackett-Jones, George Moutsopoulos +1
In this note we give a precise definition of the notion of a maximal superalgebra of certain types of supersymmetric supergravity backgrounds, including the Freund-Rubin background…
On the Lie-algebraic origin of metric 3-algebras
Paul de Medeiros, José Figueroa-O'Farrill, Elena Méndez-Escobar +1
Since the pioneering work of Bagger-Lambert and Gustavsson, there has been a proliferation of three-dimensional superconformal Chern-Simons theories whose main ingredient is a metr…
Relaxed Three-Algebras: Their Matrix Representations and Implications for Multi M2-brane Theory
M. Ali-Akbari, M. M. Sheikh-Jabbari, J. Simon
We argue that one can relax the requirements of the non-associative three-algebras recently used in constructing D=3, N=8 superconformal field theories, and introduce the notion of…
