Heat kernel and scaling of gravitational constants

We consider the nonlocal 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 nonlocal terms proportional to □scrR, □ □ scrR,...,□w-2scrR are fully determined by the early-time behavior of the hea...
