Conformally covariant differential operators: symmetric tensor fields. (English) Zbl 0912.53058
Summary: We extend previous work on conformally covariant differential operators to consider the case of second-order operators acting on symmetric traceless tensor fields. The corresponding flat space Green function is explicitly constructed and shown to be in accord with the requirements of conformal invariance.
