چکیده
We analyze supersymmetric solutions of M-theory based an a seven-dimensional internal space with SU(3) structure and a four-dimensional maximally symmetric space. The most general supersymmetry conditions are derived and we show that a non-vanishing cosmological constant requires the norms of the two internal spinors to differ. We find explicit local solutions with singlet flux and the space being a warped product of a circle, a nearly-Kähler manifold and AdS4. The embedding of solutions into heterotic M-theory is also discussed. email: [email protected] email: [email protected]

Tasi Lectures on Branes , Black Holes and Anti - De Sitter Space
In the light of the duality between physics in the bulk of anti-de Sitter space and a conformal field theory on the boundary, we review the M 2, D3 and M 5 branes and how their near-horizon geometry yields the compactification of D = 11 supergravity on S 7 , Type IIB supergravity on S 5 and D = 11 supergravity on S 4 , respectively. We discuss the " Membrane at the End of the Universe " idea an...
متن کاملDuality symmetric massive type II theories in D = 8 and D = 6 ∗
We study T 2 compactification of massive type IIA supergravity in presence of possible Ramond-Ramond (RR) background fluxes. The resulting theory in D = 8 is shown to possess full SL(2, R) × SL(2, R) T-duality symmetry similar to the massless case. It is shown that elements of duality symmetry interpolate between massive type IIA compactified on T 2 and ordinary type IIA compactified on T 2 wit...

We formulate an extension of Maldacena's AdS/CFT conjectures to the case of branes located at singular points in the ambient transverse space. For singularities which occur at finite distance in the moduli space of M or F theory models with spacetime-filling branes, the conjectures identify the worldvolume theory on the p-branes with a compactification of M or IIB theory on AdS p+2 × H D−p−2. W...
متن کاملFive-Brane Dynamics and Inflation in Heterotic M-Theory
Generic heterotic M-theory compactifications contain five-branes wrapping nonisolated genus zero or higher genus curves in a Calabi-Yau threefold. Non-perturbative superpotentials do not depend on moduli of such five-branes. We show that fluxes and non-perturbative effects can stabilize them in a non-supersymmetric AdS vacuum. We also show that these five-branes can be stabilized in a dS vacuum...
متن کاملConformality and Unification of Gauge Couplings
Conformality is inspired by superstring duality and assumes that the particle spectrum of the standard model is enriched such that there is a conformal fixed point of the renormalization group at the TeV scale. Above this scale the coupling do not run so the hierarchy is nullified. Until very recently, the possibility of testing string theory seemed at best remote. The advent of AdS/CFT s and l...
