Special invariant operators. I. (English) Zbl 0851.58049
The author’s abstract: “The aim of the first part of a series of papers is to give a description of invariant differential operators on manifolds with an almost Hermitian symmetric structure of the type $$G/B$$ which are defined on bundles associated to the reducible but undecomposable representation of the parabolic subgroup $$B$$ of the Lie group $$G$$. One example of an operator of this type is the Penrose’s local twistor transport. In this part general theory is presented, and conformally invariant operators are studied in more detail.
