Key words Riemannian manifold, curvature homogeneous manifold, locally homogeneous space MSC (2010) 53C21, 53C25, 53C30 Curvature homogeneous spaces have been studied by many authors. In this paper, we introduce and study a natural modification of this class, namely so-called curvature homogeneous spaces of type (1,3). We present a class of proper examples in every dimension and we prove a classification theorem in dimension 3 (for the generic case). We restrict ourselves to the Riemannian situation and to curvature homogeneity of order zero.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
