Verfahren zur Erweiterung der Weichteileons of Riemannian (and pseudo-Riemannian) geometry. This is mainly intended to fix the definitions and notations that we will use in the book. As a consequence, many fundamental theorems will be quoted without proofs because these are available in classical textbooks on Riemannian geometry such as [

One reason is perhaps, in the Kähler case, the relative autonomy of the Ricci tensor with regard to the metric, once the complex structure is given. The Ricci tensor—or, to be prec
