Graham, C. Robin Conformal powers of the Laplacian via stereographic projection. (English) Zbl 1133.53014 SIGMA, Symmetry Integrability Geom. Methods Appl. 3, Paper 121, 4 p. (2007). Summary: A new derivation of Branson’s factorization formula for the conformally invariant operator on the sphere whose principal part is the \(k\)-th power of the scalar Laplacian is given. The derivation deduces Branson’s formula from knowledge of the corresponding conformally invariant operator on Euclidean space (the \(k\)-th power of the Euclidean Laplacian) via conjugation by the stereographic projection mapping.
