On Several Classes of Ricci Tensor,ndition is an overdetermined PDE where the unknowns are the components of the metric. Using the methods of the theory of overdetermined PDE we can produce a lot of explicit examples, which seem to be new, of such manifolds. We will also make some observations about relationships of various conditions to each other.
