Fake Supergravity and Domain Wall Stability
We review the generalized Witten-Nester spinor stability argument for flat domain wall solutions of gravitational theories. Neither the field theory nor the solution need be supersymmetric. Nor is the space-time dimension restricted. We develop the non-trivial extension required for AdS-sliced domain walls and apply this to show that the recently proposed “Janus” solution of Type IIB supergravi...
متن کاملAxion-Dilaton Domain Walls and Fake Supergravity
Dynamical systems methods are used to investigate domain-wall solutions of a two-parameter family of models in which gravity is coupled to an axion, and to a dilaton with an exponential potential of either sign. A complete global analysis is presented for (i) constant axion and (ii) flat walls, including a study of bifurcations and a new exact domain-wall solution with non-constant axion. We re...
متن کاملFrom Fake Supergravity to Superstars
The fake supergravity method is applied to 5-dimensional asymptotically AdS spacetimes containing gravity coupled to a real scalar and an abelian gauge field. The motivation is to obtain bulk solutions with R × S3 symmetry in order to explore the AdS/CFT correspondence when the boundary gauge theory is on R × S3. A fake supergravity action, invariant under local supersymmetry through linear ord...
متن کاملTowards Holographic Renormalization of Fake Supergravity
A step is made towards generalizing the method of holographic renormalization to backgrounds which are not asymptotically AdS, corresponding to a dual gauge theory which has logarithmically running couplings even in the ultraviolet. A prime example is the background of Klebanov-Strassler (KS). In particular, a recipe is given how to calculate renormalized two-point functions for the operators d...
متن کاملFrom Wave Geometry to Fake Supergravity
The ‘Wave Geometry’ equation of the pre-WWII Hiroshima program is also the key equation of the current ‘fake supergravity’ program. I review the status of (fake) supersymmetric domain walls and (fake) pseudosupersymmetric cosmologies. An extension of the domain-wall/cosmology correspondence to a triple correspondence with instantons shows that ‘pseudosupersymmetry’ has another interpretation as...
