Pseudosymmetric locally conformal Kaehler manifolds

Many particular classes of almost Hermitian manifolds have been intensively studied. Among them, almost Hermitian manifolds whose metric is globally conformal to an almost Kaehler metric have been also encountered. But, obviously, these manifolds have the same topological properties like the almost Kaehler manifolds. Therefore, it is interesting to study almost Hermitian manifolds which are only locally conformal to an almost Kaehler manifold. The notion of a locally conformal Kaehler manifold (l.c.K-manifold) in a Hermitian manifold has been introduced by I. Vaisman in 1976. After that T. Kashiwada has determined a necessary and sufficient condition that a Hermitian manifold is an l.c.K-manifold by using the tensor equation and introduced the curvature tensor of an l.c.K-manifold with a constant holomorphic sectional curvature (an l.c.K-space form). Furthermore, T. Kashiwada and K. Matsumoto gave some properties about such a manifold. Then we can see a lot of papers about these manifolds and its submanifolds. In this thesis, some properties of l.c.K-manifolds, l.c.K-space forms and submanifolds of an l.c.K-space form are presented. Furthermore, we state some results on pseudosymmetric and Ricci-pseudosymmetric l.c.K-space forms. Walker type identities on l.c.K-space forms and Roter type l.c.K-space forms are studied. Finally the Bochner curvature tensor on l.c.K-space forms are studied.
