We compute the physical graviton two-point function in de Sitter spacetime with three-sphere spatial sections. We demonstrate that the large-distance growth present in the corresponding two-point function in spatially flat de Sitter spacetime is absent. We verify that our two-point function agrees with that in Minkowski spacetime in the zero cosmological constant limit.

Axions on de Sitter space
hep-th 2026-06 unverdicted novelty 6.0

Quantization of axions on dS_D yields Hilbert space H = L^2(S^1) ⊗ F with zero-mode U(1) charge, producing non-dS-invariant charged sectors and Hadamard Wightman functions that become asymptotically invariant.
