| contents | We show that, for any $d\geq 3$, the one-loop graviton path integral on $S^2\times S^{d-1}$ factorizes into bulk and edge parts. The bulk equals the thermal partition function of an ideal graviton gas in the Lorentzian Nariai geometry. The edge factor is the inverse of the path integral over two identical copies, each containing one shift-symmetric vector and three shift-symmetric scalars on $S^{d-1}$. Unlike the round $S^{d+1}$ case, all scalars are massless, indicating that graviton edge partition functions probe beyond the horizon's intrinsic geometry - in contrast to $p$-form gauge theories. In the course of this work, we obtain a compact formula for the one-loop Euclidean graviton path integral on any $Λ>0$ Einstein manifold. |
