Exploring the symmetry of supergravity
Walter H. Baron, Diego Marques, Carmen A. Nunez
Kaluza-Klein reductions of low energy string effective actions possess a continuous symmetry. The non-geometric elements of this group, parameterized by a bi-vector ,…
An -complete theory of cosmology and its tensionless limit
Tomas Codina, Olaf Hohm, Diego Marques
We explore the exactly duality invariant higher-derivative extension of double field theory due to Hohm, Siegel and Zwiebach (HSZ) specialized to cosmological backgrounds. Despite…
The -symmetry of supergravity
Walter H. Baron, Diego Marques, Carmen A. Nunez
Continuous O global symmetries emerge in Kaluza-Klein reductions of -dimensional string supergravities to dimensions. We show that the non-geometric elements of thi…
General String Cosmologies at Order
Tomas Codina, Olaf Hohm, Diego Marques
We compute the cosmological reduction of general string theories, including bosonic, heterotic and type II string theory to order , i.e., with up to eight derivatives. To t…
String Dualities at Order
Tomas Codina, Olaf Hohm, Diego Marques
We compute the cosmological reduction of the fourth powers of the Riemann tensor claimed to arise in string theory at order , with overall coefficient proportional to $ζ(…
Generalized Dualities and Higher Derivatives
Tomas Codina, Diego Marques
Generalized dualities had an intriguing incursion into Double Field Theory (DFT) in terms of local transformations. We review this idea and use the higher derivative formu…
