Higher Superspace Supergravity and its IR-Completions
Grigorios Giotopoulos, Hisham Sati, Urs Schreiber
It is an old idea that higher-dimensional super-gravity (SuGra) is put on-shell just by imposing Bianchi identities on super-field strengths over super-spacetimes subject to super-…
Flux Quantization on 10D Type IIA Superspace via Cyclification from 11D
Grigorios Giotopoulos, Hisham Sati
We produce the dimensional reduction to 10D IIA supergravity (SuGra), via cyclification, of the remarkable result that full 11D SuGra is put on shell just by imposing the duality-s…
The M-algebra completes the hierarchy of Super-Exceptional Tangent Spaces
Grigorios Giotopoulos, Hisham Sati, Urs Schreiber
The conjectured symmetries of M-theory famously involve (1.) brane-extended super-symmetry (the M-algebra) and (2.) exceptional duality-symmetry (the -algebra);…
The Hidden M-Group
Grigorios Giotopoulos, Hisham Sati, Urs Schreiber
Following arguments that the (hidden) M-algebra serves as the maximal super-exceptional tangent space for 11D supergravity, we make explicit here its integration to a (super-Lie) g…
Super- T-Duality and M-Theory
Grigorios Giotopoulos, Hisham Sati, Urs Schreiber
Super -algebras unify extended super-symmetry with rational classifying spaces for higher flux densities: The super-invariant super-fluxes which control super -branes…
Holographic M-Brane Super-Embeddings
Grigorios Giotopoulos, Hisham Sati, Urs Schreiber
Over a decade before the modern formulation of AdS/CFT duality, Duff et al. had observed a candidate microscopic explanation by identifying the CFT fields with fluctuations of prob…
Flux Quantization on M5-branes
Grigorios Giotopoulos, Hisham Sati, Urs Schreiber
We highlight the need for global completion of the field content in the M5-brane sigma-model analogous to Dirac's charge/flux quantization, and we point out that the superspace Bia…
Flux Quantization on 11-dimensional Superspace
Grigorios Giotopoulos, Hisham Sati, Urs Schreiber
Flux quantization of the C-field in 11d supergravity is arguably necessary for the (UV-)completion of the theory, in that it determines the torsion charges carried by small numbers…
Braided Symmetries in Noncommutative Field Theory
Grigorios Giotopoulos, Richard J. Szabo
We give a pedagogical introduction to -algebras and their uses in organising the symmetries and dynamics of classical field theories, as well as of the conventional nonco…
Braided -Algebras, Braided Field Theory and Noncommutative Gravity
Marija Dimitrijević Ćirić, Grigorios Giotopoulos, Voja Radovanović +1
We define a new homotopy algebraic structure, that we call a braided -algebra, and use it to systematically construct a new class of noncommutative field theories, that w…
Homotopy Lie Algebras of Gravity and their Braided Deformations
Marija Dimitrijević Ćirić, Grigorios Giotopoulos, Voja Radovanović +1
We describe the cyclic -algebra formulation of classical general relativity without matter fields in the Einstein-Cartan-Palatini formalism. Using Drinfel'd twist defor…
-Algebras of Einstein-Cartan-Palatini Gravity
Marija Dimitrijević Ćirić, Grigorios Giotopoulos, Voja Radovanović +1
We give a detailed account of the cyclic -algebra formulation of general relativity with cosmological constant in the Einstein-Cartan-Palatini formalism on spacetimes of…
