Conformally invariant powers of the Laplacian. I: Existence. (English) Zbl 0726.53010
A geometric derivation is given of a family of scalar conformally invariant differential operators on conformal densities with leading part a power of the Laplacian. The derivation produces an operator for each positive integral power in odd dimensions, but only for finite range of powers in even dimensions. The operators are derived from the Laplacian in the ambient metric of Fefferman-Graham via extension.
For Part II see [ibid. 46, No. 3, 566–576 (1992; Zbl 0726.53011)].
