Supertwistor realisations of AdS superspaces [PDF]
European Physical Journal C: Particles and Fields, 2022 We propose supertwistor realisations of (p, q) anti-de Sitter (AdS) superspaces in three dimensions and $${\mathcal {N}}$$ N -extended AdS superspaces in four dimensions.

Topologies on superspaces of TVS-cone metric spaces. [PDF]
ScientificWorldJournal, 2014 This paper investigates superspaces 𝒫0(X) and 𝒦0(X) of a tvs-cone metric space (X,d), where 𝒫0(X) and 𝒦0(X) are the space consisting of nonempty subsets of X and the space consisting of nonempty compact subsets of X, respectively.

Embedding formalism for (p, q) AdS superspaces in three dimensions [PDF]
Journal of High Energy Physics, 2023 We develop an embedding formalism for (p, q) anti-de Sitter (AdS) superspaces in three dimensions by using a modified version of their supertwistor description given in the literature. A coset construction for these superspaces is worked out.

Superspaces for heterotic pure spinor string compactifications [PDF]
European Physical Journal C: Particles and Fields, 2022 We study supersymmetry conditions for the heterotic pure superstring preserving $$N=1$$ N = 1 supersymmetry in four dimensions directly from the curved superspace defined by the Berkovits–Howe constraints.

Weyl covariance, and proposals for superconformal prepotentials in 10D superspaces [PDF]
Journal of High Energy Physics, 2021 Proposals are made to describe the Weyl scaling transformation laws of supercovariant derivatives ∇ A , the torsion supertensors T AB C , and curvature supertensors R ABc d in 10D superspaces. Starting from the proposal that an unconstrained supergravity

Journal of High Energy Physics, 2019 We classify N =1 d = 4 kinematical and aristotelian Lie superalgebras with spa- tial isotropy, but not necessarily parity nor time-reversal invariance. Employing a quater- nionic formalism which makes rotational covariance manifest and simplifies many of

A superspace approach to branes and supergravity [PDF]
arXiv, 2000 Recent developments in string and M theory rely heavily on supersymmetry suggesting that a revival of superspace techniques in ten and eleven dimensions may be advantageous. Here we discuss three topics of current interest where superspace is already playing an important role and where an improved understanding of superspace might provide additional ...

On harmonic superspaces and superconformal fields in four dimensions [PDF]
, 2000 Representations of four-dimensional superconformal groups on harmonic superfields are discussed. It is shown how various short representations can be obtained by parabolic induction.
