In these lecture notes we describe recent progress in our understanding of attractor mechanism and entropy of extremal black holes based on the entropy function formalism. We also describe precise computation of the microscopic degeneracy of a class of quarter BPS dyons in N = 4 supersymmetric string theories, and compare the statistical entropy of these dyons, expanded in inverse powers of electric and magnetic charges, with a similar expansion of the corresponding black hole entropy. This comparison is extended to include the contribution to the entropy from multicentered black holes as well.

We extend the correspondence between adSsupergravities and superconformal field theories on the adS boundary to a correspondence between gauged supergravities (typically with noncompact gauge groups) and quantum field theories on domain walls.
An exact holographic RG flow between 2d conformal fixed points

We describe a supersymmetric RG flow between conformal fixed points of a twodimensional quantum field theory as an analytic domain wall solution of the threedimensional SO(4)×SO(4) gauged supergravity.

We describe a supersymmetric RG flow between conformal fixed points of a twodimensional quantum field theory as an analytic domain wall solution of the threedimensional SO(4)×SO(4) gauged supergravity. Its ultraviolet fixed point is an N =(4,4) superconformal field theory related, through the double D1D5 system, to theories modeling the statistical mechanics of black holes. The flow is driven by a relevant operator of conformal dimension ∆ = 3 2 which breaks conformal symmetry and breaks supersymmetry down to N =(1,1), and sends the theory to an infrared conformal fixed point with central charge cIR = cUV/2. Using the supergravity description, we compute counterterms, onepoint functions and fluctuation equations for inert scalars and vector fields, providing the complete framework to compute twopoint correlation functions of the corresponding operators throughout the flow in the twodimensional quantum field theory. This produces a toy model for flows of N = 4 super YangMills theory in 3+1 dimensions, where conformaltoconformal flows have resisted analytical solution.
Euclideansignature supergravities, dualities and instantons

"... We study the Euclideansignature supergravities that arise by compactifying D = 11 supergravity or type IIB supergravity on a torus that includes the time direction.

We study the Euclideansignature supergravities that arise by compactifying D = 11 supergravity or type IIB supergravity on a torus that includes the time direction. We show that the usual Tduality relation between type IIA and type IIB supergravities compactified on a spatial circle no longer holds if the reduction is performed on the time direction. Thus there are two inequivalent Euclideansignature ninedimensional maximal supergravities. They become equivalent upon further spatial compactification to D = 8. We also show that duality symmetries of Euclideansignature supergravities allow the harmonic functions of any singlecharge or multicharge instanton to be rescaled and shifted by constant factors. Combined with the usual diagonal dimensional reduction and oxidation procedures, this allows us to use the duality symmetries to map any singlecharge or multicharge pbrane soliton, or any intersection, into its nearhorizon regime. Similar transformations can also be made on nonextremal pbranes. We also study the structures of duality multiplets of instanton and (D − 3)brane solutions.

We present a new 1/8 supersymmetric intersecting Mbrane solution of D=11 supergravity with two independent rotation parameters. The metric has a nonsingular event horizon and the nearhorizon geometry is adS3 ×S 3 ×S 3 ×E 2 (just as in the nonrotating case). We also present a method of determining the isometry supergroup of supergravity solutions from the Killing spinors and use it to show that for the near horizon solution it is D(21, α) × D(21, α) where α is the ratio of the two 3sphere radii. We also consider various dimensional reductions of our solution, and the corresponding effect of these reductions on the Killing spinors and the isometry supergroups.
