Recently, a perturbative duality between gauge and gravity theories (the double copy) has been discovered, that is believed to hold to all loop orders. In
More algebra gives the invariant interval in terms of t+ and r, ds2=(1−2GMc2r)dt+2−2dt+dr−r2(dθ2+sin2θdφ2) which is named after its discoverers, the “Eddington–Finkelstein” representation [6]. Again there are no false singularities here and light rays, ds2 = 0, ...
We construct two-dimensional quantum states associated to four-dimensional linearized rotating self-dual black holes in (2, 2) signature Klein space. The states are comprised of global conformal primaries circulating on the celestial torus, the Kleinian analog of the celestial sphere. By introducing...
We analyse in detail the SL(2, ja:math ) black hole by extending standard techniques of Kac-Moody current algebra to the non-compact case. We construct the elements of the ground ring and exhibit W ∞ type structure in the fusion algebra of the discrete states. As a consequence, we can...
We consider a deformation of the well-known stu model of N = 2, D = 4 supergravity, characterized by a non-homogeneous special Khler manifold, and by the smallest electric-magnetic duality Lie algebra consistent with its upliftability to five dimensions. We explicitly solve the BPS attractor ...
Finally, we have drawn our conclusions in Section 5. 2. Thermodynamic Variables of Higher Curvature Charged AdS Black Holes The effective action in the Lovelock gravity in ( + 1) dimen- sions can be written as (here we have taken the gravitational constant = 1) [4] I = 1 16 [( +...
In the 1960s research in this direction became rather intensive. This area was known under different names: symbolic calculations, analytic calculations, and computer algebra. Recently this last name is most widely used. Why... DOI: 10.1112/plms/s3-62.3.647 被引量: 51 年份: 1991 ...

Journal of High Energy Physics Frederik Denef, Mboyo Esole& Megha Padi Abstract By T-dualizing space-filling D-branes in 4d IIB orientifold compactifications along the three non-internal spatial directions, we obtain black hole bound states living in a universe with a gauged spatial reflection ...
Higher-order derivative terms are considered as replacement for the Skyrme term in an Einstein-Skyrme-like model in order to pinpoint which properties are
