On the curvature operator of the second kind
Webthe curvature of the manifold. This term is often called the Weitzenböck curvature operator on forms. This curvature operator will be extended to tensors. When this term is added to the connection Laplacian we obtain one version of what is called the Lichnerowicz Laplacian. One step in our reduction is modeled on W.A. Poor’s approach to the ... Websecond F0 term. We note that using the Grassmann algebra multiplication we have a map V 2 C 4 V 2 C ! V 4 C : The even Grassmann algebra is commutative. Hence, this induces an intertwin-ing operator S 2(V C 4) ! V C4: This is the other F0. On can show that the kernel of this map is exactly the space of curvature operators satisfying the Bianchi ...
