The large N limit of superconformal field theories and supergravity
, 1998
"... We show that the large N limit of certain conformal field theories in various dimensions include in their Hilbert space a sector describing supergravity on the product of AntideSitter spacetimes, spheres and other compact manifolds. This is shown by taking some branes in the full M/string theory and ..."

in the superconformal group (as opposed to just the superPoincare group). The ’t Hooft limit of 3+1 N = 4 superYangMills at the conformal point is shown to contain strings: they are IIB strings. We conjecture that compactifications of M/string theory on various AntideSitter spacetimes is dual to various conformal
Polyvector superPoincaré algebras
 Comm. Math. Phys
, 2005
"... A class of Z2graded Lie algebra and Lie superalgebra extensions of the pseudoorthogonal algebra of a spacetime of arbitrary dimension and signature is investigated. They have the form g = g0 + g1, with g0 = so(V) + W0 and g1 = W1, where the algebra of generalized translations W = W0 + W1 is the max ..."

classification of such Lie (super)algebras for all dimensions and signatures. The problem reduces to the classification of so(V)invariant ∧ k Vvalued bilinear forms on the spinor module S.Contents
Notes on Spinors
"... In these notes, we collect the properties of spinors in various dimensions and, over JR, for spaces of various signatures. Such information is needed to discuss the possihle supersymmetries in various dimensions (super Poincare groups), and the possible Lorentz invariant kinetic and mass terms for f ..."

and generalized InönüWigner contraction
, 2001
"... We examine a WessZumino term, written in bilinear of superinvariant currents, for a superstring in antide Sitter (AdS) space. The standard InönüWigner contraction does not give the correct flat limit but gives zero. This originates from the fact that the fermionic metric of the superPoincaré gro ..."

group is degenerate. We propose a generalization of the InönüWigner contraction which reduces the superAdS group to the “nondegenerate” superPoincaré group, therefore it gives a correct flat limit of this WessZumino term. We also discuss the Malgebra obtained by this generalized Inönü
Gravity as a Gauge Theory with Spontaneously Broken Internal SuperPoincare Symmetry
"... An effective gauge theory of gravity is constructed with the aid of the method of nonlinear realizations. The internal super · Poincare gauge symmetry breaks down spontaneously to the Lorentz one. The co·frame ekp is constructed out of gauge fields, NambuGoldstone fields and a spectator field so th ..."

that it leads to a superPoincare gauge invariant metric. This ek p remains invariant under supertransformations, and thus its superpartner is not needed, in contrast to the case of conventional supergravity. Further, the internal supersymmetry does not require photino, Wino, Zino, "', in contrast
IFUSPP1143 SuperPoincaré Invariant Superstring Field Theory
, 1995
"... Using the topological techniques developed in an earlier paper with Vafa, a field theory action is constructed for any open string with critical N=2 worldsheet superconformal invariance. Instead of the ChernSimonslike action found by Witten, this action resembles that of a WessZuminoWitten model ..."

Representations of pbrane topological charge algebras
, 2005
"... The ideals of the known extended algebras associated with pbranes are given representations in terms of superspace forms. These forms are used to construct representatives of the anomalous terms of the pbrane topological charge algebras. The forms also represent Noether charges of Under the action ..."

the action of the superPoincaré group, the pbrane Lagrangian is invariant only up to a total derivative. As a result of this “quasiinvariance, ” the Noether charge algebra of the pbrane is modified by a topological “anomalous term ” [1]. The anomalous term also appears as the result of solving
The Structure of SpaceTime Emerging from the TwoSuperbody Problem
, 1996
"... We show that the exact solution of the twosuperbody problem in N = 2 Chern Simons supergravity in 2+1 dimensions leads to a supermultiplet of spacetimes characterized by the two gauge invariant observables of the super Poincaré group. The metric of this spacetime supermultiplet can be cast into t ..."
