Heat kernel and scaling of gravitational constants.
We consider the non-local energy-momentum tensor of quantum scalar and spinor fields in 2w-dimensional curved spaces. Working to lowest order in the curvature we show that, while the non-local terms proportional to 2R, 22R, . . . ,2w−2R are fully determined by the early-time behaviour of the heat kernel, the terms proportional to R depend on the asymptotic latetime behaviour. This fact explains...
متن کاملGravitational scaling dimensions
A model for quantized gravitation based on simplicial lattice discretization is studied in detail using a comprehensive finite size scaling analysis combined with renormalization group methods. The results are consistent with a value for the universal critical exponent for gravitation, n51/3, and suggest a simple relationship between Newton’s constant, the gravitational correlation length and t...
متن کاملHeat Kernel
In this paper, by rst deriving a global version of gradient estimates, we obtain both upper and lower bound estimates for the heat kernel satisfying Neumann boundary conditions on a compact Riemannian manifold with nonconvex boundary .
متن کاملGravitational and Kinetic Scaling of Physical Units
One of Einstein’s great innovations in relativity theory was to break with the idea that there is an exchange of kinetic and potential energy as an object changes its position in a gravitational field. Instead, he assumed that the unit of energy varies in a systematic manner that can be deduced from Newton’s Universal Law of Gravitation and his own famous mass/energy equivalence relation. In th...
متن کاملHeat Kernel and Moduli Spaces
In this paper we describe a proof of the formulas of Witten [W1], [W2] about the symplectic volumes and the intersection numbers of the moduli spaces of principal bundles on a compact Riemann surface. It is known that these formulas give all the information needed for the Verlinde formula. The main idea of the proof is to use the heat kernel on compact Lie groups, in a way very similar to the h...
