Integrable properties of sigma-models with non-symmetric target spaces
Dmitri Bykov
It is well-known that sigma-models with symmetric target spaces are classically integrable. At the example of the model with target space the flag manifold U(3)/U(1)^3 -- a non-sym…
Grassmannian Integrals as Matrix Models for Non-Compact Yangian Invariants
Nils Kanning, Yumi Ko, Matthias Staudacher
In the past years, there have been tremendous advances in the field of planar N=4 super Yang-Mills scattering amplitudes. At tree-level they were formulated as Grassmannian integra…
Dimensional flow in discrete quantum geometries
Gianluca Calcagni, Daniele Oriti, Johannes Thürigen
In various theories of quantum gravity, one observes a change in the spectral dimension from the topological spatial dimension at large length scales to some smaller value at s…
Standard Model Fermions and N=8 supergravity
Krzysztof A. Meissner, Hermann Nicolai
In a scheme originally proposed by M. Gell-Mann, and subsequently shown to be realized at the SU(3)xU(1) stationary point of maximal gauged SO(8) supergravity by N. Warner and one…
Filtrations in Dyson-Schwinger equations: next-to^{j} -leading log expansions systematically
Olaf Krueger, Dirk Kreimer
Dyson-Schwinger equations determine the Green functions in quantum field theory. Their solutions are triangular series in a coupling constant and an external scale p…
Canonical structure of the E10 model and supersymmetry
Axel Kleinschmidt, Hermann Nicolai, Nitin K. Chidambaram
A coset model based on the hyperbolic Kac-Moody algebra E10 has been conjectured to underly eleven-dimensional supergravity and M theory. In this note we study the canonical struct…
