We introduce an infinite-dimensional Lie superalgebra which is an extension of the U-duality Lie algebra of maximal supergravity in D dimensions, for 3 ⩽ D ⩽ 7. The level decomposition with respect to the U-duality Lie algebra gives exactly the tensor hierarchy of representations that arises in gauge deformations of the theory described by an embedding tensor, for all positive levels p. We prove that these representations are always contained in those coming from the associated Borcherds-Kac… Expand

In the present paper, we dwelve into the relationship between tensor hierarchy structures in supergravity theories, and Leibniz algebras. The tensor hierarchies naturally emerge from gaugingExpand
The gauge structure of exceptional field theories and the tensor hierarchy
A bstractWe address the construction of manifest U-duality invariant generalized diffeomorphisms. The closure of the algebra requires an extension of the tangent space to include a tensor hierarchyExpand
The Embedding Tensor, Leibniz–Loday Algebras, and Their Higher Gauge Theories
We show that the data needed for the method of the embedding tensor employed in gauging supergravity theories are precisely those of a Leibniz algebra (with one of its induced quotient Lie algebrasExpand
Tensor hierarchy algebras and extended geometry. Part I. Construction of the algebra
Tensor hierarchy algebras constitute a class of non-contragredient Lie superalgebras, whose finite-dimensional members are the “Cartan-type” Lie superalgebras in Kac’s classification. They haveExpand
Forms and algebras in (half-)maximal supergravity theories
A bstractThe forms in D-dimensional (half-)maximal supergravity theories are discussed for 3 ≤ D ≤ 11. Superspace methods are used to derive consistent sets of Bianchi identities for all the formsExpand

Tensor hierarchy extensions of hyperbolic Kac–Moody algebras
Tensor hierarchy algebras are infinite-dimensional generalisations of Cartan-type Lie superalgebras. They are not contragredient, exhibiting an asymmetry between positive and negative levels. TheseExpand
Hidden Q-structure and Lie 3-algebra for non-abelian superconformal models in six dimensions

Tensor hierarchies and Lie $n$-extensions of Leibniz algebras
Tensor hierarchies are algebraic objects that emerge in gauging procedures in supergravity models, and that present a very deep and intricate relationship with Leibniz (or Loday) algebras. In thisExpand


Half-maximal supergravity in three dimensions: supergeometry, differential forms and algebraic structure
A bstractThe half-maximal supergravity theories in three dimensions, which have local SO(8) × SO(n) and rigid SO(8, n) symmetries, are discussed in a superspace setting starting from theExpand
The E11 origin of all maximal supergravities. The hierarchy of field-strengths
Starting from E11 and the space-time translations we construct an algebra that promotes the global E11 symmetries to local ones, and consider all its possible massive deformations. The JacobiExpand
