3D gauged supergravity from SU(2) reduction of N = 1 6D supergravity
We obtain Yang-Mills SU(2) × G gauged supergravity in three dimensions from SU(2) group manifold reduction of (1,0) six dimensional supergravity coupled to an anti-symmetric tensor multiplet and gauge vector mult...

Two dimensional RG flows and Yang-Mills instantons
We study RG flow solutions in (1,0) six dimensional supergravity coupled to an anti-symmetric tensor and Yang-Mills multiplets corresponding to a semisimple group G. We turn on G instanton gauge fields, with inst...

Gravitational and Yang-Mills instantons in holographic RG flows
We study various holographic RG flow solutions involving warped asymptotically locally Euclidean (ALE) spaces of A N − 1 type. A two-dimensional RG flow from a ...

Holography and conformal anomaly matching
We discuss various issues related to the understanding of the conformal anomaly matching in CFT from the dual holographic viewpoint. First, we act with a PBH diffeomorphism on a generic 5D RG flow geometry and...

Open AccessBlack holes in the 3D higher spin theory and their quasi normal modes
We present a class of 3D black holes based on flat connections which are poly-nomials in the BTZ hs(λ) × hs(λ)-valued connection. We solve analytically the fluctuation equations of matter in their background and ...

Open AccessReal topological string amplitudes
We discuss the physical superstring correlation functions in type I theory (or equivalently type II with orientifold) that compute real topological string amplitudes. We consider the correlator corresponding to h...

Open AccessDiscontinuities of free theories on AdS2
The partition functions of free bosons as well as fermions on AdS2 are not smooth as a function of their masses. For free bosons, the partition function on AdS2 is not smooth when the mass saturates the Breitenlo...
