We examine a limitting procedure of superalgebras for a BPS-particle in AdS2 × S2, pp-wave and flat backgrounds focussing on BPS-brane charges. The BPS-particle charge in the flat superalgebra is traced back to a part of Lorentz rotation generators in the AdS and pp-wave superalgebras. A Wess-Zumino term for a BPS-brane causes a momentum shift and the contribution is absorbed into bosonic generators, then it results in closure of the AdS and pp-wave superalgebras. 
Anti-de-Sitter vacua require fermionic brane charges
We argue that a modification of the super-AdS algebras which accounts for the presence of D-branes requires not only the inclusion of bosonic brane charges, but also the inclusion of new fermionicExpand
Wess–Zumino terms for AdS D-branes
We show that Wess–Zumino terms for Dp branes with p>0 in the anti-de Sitter (AdS) space are given in terms of “left-invariant” currents on the super-AdS group or the “expanded” super-AdS group. As aExpand
Classical Integrability and Super Yangian of Superstring on AdS_5 x S^5
We discuss a classical integrability in the type IIB string theory on the AdS_5 x S^5 background. By using the Roiban-Siegel formulation of the superstring on the AdS_5 x S^5, we carefully treat theExpand
N=4 superconformal mechanics as a non linear realization
An action for a superconformal particle is constructed using the non linear realization method for the group PSU(1,1|2), without introducing superfields. The connection between PSU(1,1|2) and blackExpand
Superstrings in AdS2 × S2 × T6
We consider the type IIB Green–Schwarz superstring theory on AdS2 × S2 × T6 supported by homogeneous Ramond–Ramond 5-form flux and its type IIA T-duals. One motivation is to understand the solutionExpand

Dp-branes in PP wave background
Abstract Dirichlet p-branes in the background of pp-waves are constructed using the massive Green–Schwarz world-sheet action for open strings. These branes are localized at the origin and only for pExpand
Super-pp-wave algebra from super-AdS×S algebras in eleven dimensions
Abstract Maximally supersymmetric spacetime algebras in eleven dimensions, which are the isometry superalgebras of Minkowski space, AdS7×S4, AdS4×S7 and pp-wave background, are related byExpand
Branes from matrix theory in pp-wave background
Based on the recently proposed action for matrix theory describing the DLCQ M-theory in the maximally supersymmetric pp-wave background, we obtain the supersymmetry algebra of supercharge density.Expand
From super-AdS5×S5 algebra to super-pp-wave algebra
The isometry algebras of the maximally supersymmetric solutions of IIB supergravity are derived by the Inonu–Wigner contractions of the super-AdS5×S5 algebra. The super-AdS5×S5 algebra allowsExpand
Open strings in a pp-wave background from defect conformal field theory
We consider open strings ending on a D5-brane in the pp-wave background, which is realized in the Penrose limit of AdS5×S5 with an AdS4×S2 brane. A complete set of gauge invariant operators in theExpand
D-brane solutions in pp-wave background
Abstract We present classical solutions for a D5- and NS5-branes in a pp-wave background. The worldvolume coordinates for these branes lie along a six-dimensional pp-wave configuration obtained fromExpand
M-theory on less supersymmetric pp-waves
Abstract There are fractionally supersymmetric pp-waves in 11-dimensional supergravity. We study the corresponding supersymmetric Yang–Mills matrix dynamics for M-theory and find its superalgebra andExpand
