The quantum chiral Minkowski and conformal superspaces [PDF]
We give a quantum deformation of the chiral super Minkowski space in four dimensions as the big cell inside a quantum super Grassmannian. The quantization is performed in such way that the actions of the Poincar\'e and conformal quantum supergroups on ...

Strings on semisymmetric superspaces [PDF]
Several string backgrounds which arise in the AdS/CFT correspondence are described by integrable sigma-models. Their target space is always a $$ {\mathbb{Z}_4} $$ supercoset (a semi-symmetric superspace). Here we list all semi-symmetric cosets which have

On Chiral Quantum Superspaces [PDF]
We give a quantum deformation of the chiral Minkowski superspace in 4 dimensions embedded as the big cell into the chiral conformal superspace. Both deformations are realized as quantum homogeneous superspaces: we deform the ring of regular functions ...

Supersymmetry in noncommutative superspaces [PDF]
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.

On Five-dimensional Superspaces [PDF]
Recent one-loop calculations of certain supergravity-mediated quantum corrections in supersymmetric brane-world models employ either the component formulation (hep-th/0305184) or the superfield formalism with only half of the bulk supersymmetry ...

Noncommutative spaces and superspaces from Snyder and Yang type models [PDF]
The relativistic 𝐷 = 4 Snyder model is formulatedin terms of 𝐷 = 4 𝑑𝑆 algebra 𝑜 ( 4 , 1 ) generators, with noncommutative Lorentz-invariant Snyder quantum space-time provided by 𝑂 ( 4 , 1 ) 𝑂 ( 3 , 1 ) coset generators. Analogously, in relativistic 𝐷 = 4

The low-energy N = 4 SYM effective action in diverse harmonic superspaces [PDF]
We review various superspace approaches to the description of the low-energy effective action in N = 4 super Yang–Mills (SYM) theory. We consider the four-derivative part of the low-energy effective action in the Coulomb branch. The typical components of

Spinorial Snyder and Yang models from superalgebras and noncommutative quantum superspaces
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 ...
