On the natural operators of Bianchi type. (English) Zbl 0810.58003
Summary: We determine all natural operators $$J^ 1 Y \to VY \otimes \wedge^ 3 T^*X$$ for a fibred manifold $$Y \to X$$. We prove that the only operator of this type is the zero operator. This gives another proof of the Bianchi identity for generalized connections.
