Maximally symmetric spin-two bitensors on S3 and H3.
نویسنده
چکیده
The transverse traceless spin-two tensor harmonics on S3 and H3 may be denoted by T ab. The index k labels the (degenerate) eigenvalues of the Laplacian and l the other indices. We compute the bitensor ∑ l T (kl) ab(x)T (kl) a′b′(x ) where x, x are distinct points on a sphere or hyperboloid of unit radius. These quantities may be used to find the correlation function of a stochastic background of gravitational waves in spatially open or closed Friedman-Robertson-Walker cosmologies.

Work function and surface energy per unit area were calculated in the framework of density functional theory (DFT) with Linearized A ug mented Plane Wave Plus Local Orbital method in full potential for a clean symmetric slab of silicon containing two (top and bottom) surfaces. The surfaces were theoretically modeled using supercell technique by stacking a variety of silicon layers along (111)...
متن کاملOn Symmetric Group S3 Actions on Spin 4-manifolds
Let X be a smooth, closed, connected spin 4-manifold with b1(X) = 0 and non-positive signature σ(X). In this paper we use Seiberg-Witten theory to prove that if X admits an odd type symmetric group S3 action preserving the spin structure, then b+2 (X) ≥ |σ(X)|/8 + 3 under some non-degeneracy conditions. We also obtain some information about IndS̃3 D, where S̃3 is the extension of S3 by Z2.
متن کاملPositivity of relativistic spin network evaluations
LetG be a compact Lie group. Using suitable normalization conventions, we show that the evaluation of G×G-symmetric spin networks is non-negative whenever the edges are labeled by representations of the form V ⊗ V ∗ where V is a representation of G, and the intertwiners are generalizations of the Barrett–Crane intertwiner. This includes in particular the relativistic spin networks with symmetry...
متن کاملThe Hagedorn temperature in a decoupled sector of AdS/CFT
We match the Hagedorn/deconfinement temperature of planarN = 4 super Yang-Mills (SYM) on R × S3 to the Hagedorn temperature of string theory on AdS5 × S5. The match is done in a near-critical region where both gauge theory and string theory are weakly coupled. On the gauge theory side we are taking a decoupling limit found in Ref. [7] in which the physics of planar N = 4 SYM is given exactly by...
متن کاملPropagators for p-forms in AdS2p+1 and correlation functions in the AdS7/(2,0) CFT correspondence
In AdS2p+1 we construct propagators for p-forms whose lagrangians contain terms of the form A ∧ dA. In particular we explore the case of forms satisfying “self duality in odd dimensions”, and the case of forms with a topological mass term. We point out that the “complete” set of maximally symmetric bitensors previously used in all the other propagator papers is incomplete there exists another b...
