On conformal powers of the Dirac operator on Einstein manifolds

Abstrakt

We determine the structure of conformal powers of the Dirac operator on Einstein Spin-manifolds in terms of the product formula for shifted Dirac operators. The result is based on the techniques of higher variations for the Dirac operator on Einstein manifolds and spectral analysis of the Dirac operator on the associated Poincar,-Einstein metric, and relies on combinatorial recurrence identities related to the dual Hahn polynomials.
