For odd dimensional Poincaré–Einstein manifolds (Xn+​1,g), we study the set of harmonic k-forms (for k/2) which are Cm (with m∈N) on the conformal compactification Xˉ of X. This is infinite dimensional for small m but it becomes finite dimensional if m is large enough, and in one-to-one correspondence with the direct sum of the relative cohomology Hk(Xˉ,∂Xˉ) and the kernel of the Branson–Gover [3] differential operators (Lk​,Gk​) on the conformal ifinity (∂Xˉ,[h0​]). In a second time we relate the set of Cn−2k+1(Λk(Xˉ)) forms in the kernel of d+δg​ to the conformal harmonics on the boundary in the sense of [3], providing some sort of long exact sequence adapted to this setting. This study also provides another construction of Branson–Gover differential operators, including a parallel construction of the generalization of Q-curvature for forms.
