Supersymmetry in noncommutative superspaces

Journal of High Energy Physics, 2003
Non commutative superspaces can be introduced as the Moyal-Weyl quantization of a Poisson bracket for classical superfields. Different deformations are studied corresponding to constant background fields in string theory.

Spherical functions on homogeneous superspaces [PDF]

Journal of Mathematical Physics, 2005
Homogeneous superspaces arising from the general linear supergroup are studied within a Hopf algebraic framework. Spherical functions on homogeneous superspaces are introduced, and the structures of the superalgebras of the spherical functions on classes

Three-dimensional (p, q) AdS superspaces and matter couplings

Journal of High Energy Physics, 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 XIJKL = 0 are conformally flat.

On harmonic superspaces and superconformal fields in four dimensions

Classical and Quantum Gravity, 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.

Supergravity with and without superspace

Annals of Physics, 1980
We show that the superspace formalism follows from the component formalism. After constructing the supervielbeins and superconnections off-shell in second-order formalism with the minimal set of auxiliary fields, we show that the resulting supertorsions satisfy the constraints of the various equivalent superspace approaches.

Dirac quantization in superspace

Physical Review D, 1986
We extend the method of Dirac quantization to superspace. We study simple models like the supersymmetric quantum mechanics as well as the supersymmetric nonlinear \ensuremath{\sigma} model in 1+1 dimensions. Although in both these cases the matrix representing the Poisson brackets between the constraints is singular, we show, following the spirit of ...

Fundamental regions of superspace

Physical Review D, 1990
We consider the fundamental region for the space of spatial metrics over ({ital d}{minus}1)-dimensional tori in order to normalize the universal wave function.
