Strange higher-spin topological systems in 3D
Nicolas Boulanger, Andrea Campoleoni, Victor Lekeu +1
Motivated by the generation of action principles from off-shell dualisation, we present a general class of free, topological theories in three dimensional Minkowski spacetime that…
Gravitational anomalies of fermionic higher-spin fields
Victor Lekeu, Yi Zhang
Using the Atiyah-Singer index theorem, we formally compute gravitational anomalies for fermionic higher-spin fields in two, six and ten dimensions, as well as the U(1) mixed gauge-…
On the quantisation and anomalies of antisymmetric tensor-spinors
Victor Lekeu, Yi Zhang
We perform the quantisation of antisymmetric tensor-spinors (fermionic -forms) using the Batalin-Vilkovisky field-antifield formalism. Just as for the grav…
Homotopy Transfer and Effective Field Theory II: Strings and Double Field Theory
Alex S. Arvanitakis, Olaf Hohm, Chris Hull +1
We continue our study of effective field theory via homotopy transfer of -algebras, and apply it to tree-level non-Wilsonian effective actions of the kind discussed by Se…
Higher spins from exotic dualisations
Nicolas Boulanger, Victor Lekeu
At the free level, a given massless field can be described by an infinite number of different potentials related to each other by dualities. In terms of Young tableaux, dualities r…
Homotopy Transfer and Effective Field Theory I: Tree-level
Alex S. Arvanitakis, Olaf Hohm, Chris Hull +1
We use the dictionary between general field theories and strongly homotopy algebras to provide an algebraic formulation of the procedure of integrating out of degrees of freedom in…
A note on the double dual graviton
Marc Henneaux, Victor Lekeu, Amaury Leonard
The (free) graviton admits, in addition to the standard Pauli-Fierz description by means of a rank-two symmetric tensor, a description in which one dualizes the corresponding (2,2)…
Three-dimensional conformal geometry and prepotentials for four-dimensional fermionic higher-spin fields
Marc Henneaux, Victor Lekeu, Amaury Leonard +2
We introduce prepotentials for fermionic higher-spin gauge fields in four spacetime dimensions, generalizing earlier work on bosonic fields. To that end, we first develop tools for…
Aspects of electric-magnetic dualities in maximal supergravity
Victor Lekeu
This thesis is devoted to various aspects of electric-magnetic duality and its gravitational generalization, with an emphasis on the case of maximal supergravity. It is divided int…
The Action of the (Free) Theory in Six Spacetime Dimensions
Marc Henneaux, Victor Lekeu, Javier Matulich +1
The action of the free theory in six spacetime dimensions is explicitly constructed. The variables of the variational principle are prepotentials adapted to t…
Prepotentials for linearized supergravity
Victor Lekeu, Amaury Leonard
Linearized supergravity in arbitrary dimension is reformulated into a first order formalism which treats the graviton and its dual on the same footing at the level of the action. T…
Deformations of vector-scalar models
Glenn Barnich, Nicolas Boulanger, Marc Henneaux +3
Abelian vector fields non-minimally coupled to uncharged scalar fields arise in many contexts. We investigate here through algebraic methods their consistent deformations ("gauging…
The Action of the (free) -theory
Marc Henneaux, Victor Lekeu, Amaury Leonard
The theory in six dimensions is an exotic theory of supergravity that has been argued to emerge as the strong coupling limit of theories having supergravity as their…
A note on "gaugings" in four spacetime dimensions and electric-magnetic duality
Marc Henneaux, Bernard Julia, Victor Lekeu +1
The variety of consistent "gauging" deformations of supergravity theories in four dimensions depends on the choice of Lagrangian formulation. One important goal is to get the most…
Chiral Tensors of Mixed Young Symmetry
Marc Henneaux, Victor Lekeu, Amaury Leonard
Chiral tensors of mixed Young symmetry, which exist in the same spacetime dimensions where chiral -forms can be defined, are investigated. Such chiral tensors have been…
invariant non-extremal entropy
G. Compère, V. Lekeu
The entropy of generic non-extremal dyonic black holes in the STU model has been shown to admit a remarkably universal form. The missing invariant in the formula was recently ident…
Enhancement of hidden symmetries and Chern-Simons couplings
Marc Henneaux, Axel Kleinschmidt, Victor Lekeu
We study the role of Chern--Simons couplings for the appearance of enhanced symmetries of Cremmer--Julia type in various theories. It is shown explicitly that for generic values of…
Kac-Moody and Borcherds Symmetries of Six-Dimensional Chiral Supergravity
Marc Henneaux, Victor Lekeu
We investigate the conjectured infinite-dimensional hidden symmetries of six-dimensional chiral supergravity coupled to two vector multiplets and two tensor multiplets, which is kn…
