abstract
We describe our recent calculation of two-loop corrections to the expansion rate of an initially inflating universe on the manifold $T^3 \times \Re$. If correct, our result proves that quantum gravitational effects slow the rate of inflation by an amount which becomes non-perturbatively large at late times. In a preliminary discussion of basic issues we show that the expansion rate is a gauge invariant, and that our ultraviolet regulator does not introduce spurious time dependence. We also derive a sharp bound on the maximum strength of higher loop effects.

UNVERDICTED 3representative citing papers
Derives a relatively simple graviton propagator in de Sitter space for a one-parameter family of non-covariant gauges to enable gauge-dependence checks in loop computations.
A single power-law effective scaling anchored at today's Hubble rate is extrapolated to inflation and required to match the Starobinsky plateau within O(1) factors, selecting γ ≈ 0.49 and β ≈ 0.68.
