New perspectives in Kac-Moody algebras associated to higher dimensional manifolds
Rutwig Campoamor-Stursberg, Alessio Marrani, Michel Rausch de Traubenberg
In this review, we present a general framework for the construction of Kac-Moody (KM) algebras associated to higher-dimensional manifolds. Starting from the classical case of loop…
Incidence geometry of the Fano plane and Freudenthal's ansatz for the construction of (split) octonions
Michel Rausch de Traubenberg, Marcus J. Slupinski
In this article we consider structures on a Fano plane which allow a generalisation of Freudenthal's construction of a norm and a bilinear multiplication law on an eight…
A pedagogical discussion of N = 1 four-dimensional supergravity in superspace
Robin Ducrocq, Michel Rausch de Traubenberg, Mauricio Valenzuela
A short introduction to N = 1 supergravity in four dimensions in the superspace approach is given emphasising on all steps to obtain the final Lagrangian. In particular starting fr…
Three-loop Euler-Heisenberg Lagrangian in 1+1 QED, part 1: single fermion-loop part
Idrish Huet, Michel Rausch de Traubenberg, Christian Schubert
We study the three-loop Euler-Heisenberg Lagrangian in spinor quantum electrodynamics in 1+1 dimensions. In this first part we calculate the one-fermion-loop contribution, applying…
Asymptotic behavior of the QED perturbation series
Idrish Huet, Michel Rausch de Traubenberg, Christian Schubert
In this talk, I will summarize the present state of a long-term effort to obtain information on the high-order asymptotic behaviour of the QED perturbation series through the effec…
Hidden quartic symmetry in N=2 supersymmetry
Rutwig Campoamor-Stursberg, Michel Rausch de Traubenberg
It is shown that for N=2 supersymmetry a hidden symmetry arises from the hybrid structure of a quartic algebra. The implications for invariant Lagrangians and multiplets are explor…
