Supergravities and branes from Hilbert-Poincaré series
Journal of High Energy Physics, 2023 The Molien-Weyl integral formula and the Hilbert-Poincaré series have proven to be powerful mathematical tools in relation to gauge theories, allowing to count the number of gauge invariant operators.

Three-dimensional (p,q) AdS superspaces and matter couplings [PDF]
, 2012 We introduce N-extended (p,q) AdS superspaces in three space-time dimensions, with p+q=N and p>=q, and analyse their geometry. We show that all (p,q) AdS superspaces with X^{IJKL}=0 are conformally flat.

Spinorial Snyder and Yang models from superalgebras and noncommutative quantum superspaces
Physics Letters B, 2022 The relativistic Lorentz-covariant quantum space-times obtained by Snyder can be described by the coset generators of (anti) de-Sitter algebras. Similarly, the Lorentz-covariant quantum phase spaces introduced by Yang, which contain additionally quantum ...

The Minkowski and conformal superspaces [PDF]
Journal of Mathematical Physics, 2007 We define complex Minkowski superspace in four dimensions as the big cell inside a complex flag supermanifold. The complex conformal supergroup acts naturally on this superflag, allowing us to interpret it as the conformal compactification of complex Minkowski superspace. We then consider real Minkowski superspace as a suitable real form of the complex

AdS (super)projectors in three dimensions and partial masslessness
Journal of High Energy Physics, 2021 We derive the transverse projection operators for fields with arbitrary integer and half-integer spin on three-dimensional anti-de Sitter space, AdS3. The projectors are constructed in terms of the quadratic Casimir operators of the isometry group SO(2 ...

Self-duality in Generalized Lorentz Superspaces [PDF]
, 1996 We extend the notion of self-duality to spaces built from a set of representations of the Lorentz group with bosonic or fermionic behaviour, not having the traditional spin-one upper-bound of super Minkowski space.

Strings on semisymmetric superspaces [PDF]
Journal of High Energy Physics, 2010 Several string backgrounds which arise in the AdS/CFT correspondence are described by integrable sigma-models. Their target space is always a Z(4) supercoset (a semi-symmetric superspace). Here we list all semi-symmetric cosets which have zero beta function and central charge c<=26 at one loop in perturbation theory.

Dissipative hydrodynamics in superspace [PDF]
Journal of High Energy Physics, 2018 AbstractWe construct a Schwinger-Keldysh effective field theory for relativistic hydrodynamics for charged matter in a thermal background using a superspace formalism. Superspace allows us to efficiently impose the symmetries of the problem and to obtain a simple expression for the effective action.

An entropy current in superspace [PDF]
Journal of High Energy Physics, 2019 Abstract We provide a mechanism by which an entropy current can be constructed in a supersymmetric formulation of the low-energy effective action for the Schwinger-Keldysh generating functional. This mechanism allows us to define an entropy current quantum mechanically by coupling it to an external source.

N = 1 $$ \mathcal{N}=1 $$ Liouville SCFT in four dimensions
Journal of High Energy Physics, 2018 We construct a four supercharges Liouville superconformal field theory in four dimensions. The Liouville superfield is chiral and its lowest component is a log-correlated complex scalar whose real part carries a background charge.
