  In this paper we study a generalization of the classical Rarita-Schwinger
type operators and construct their fundamental solutions. We give some basic
integral formulas related to these operators. We also establish that the
projection operators appearing in the Rarita-Schwinger operators and the
Rarita-Schwinger equations are conformally invariant. We further obtain the
intertwining operators for other operators related to the Rarita-Schwinger
operators under actions of the conformal group.
