 books.google.com Hence, since a psasakian manifold has a positive definite metric, we find either

have now the following theorem : A recurrent Psasakian manifold does not exist. 

 books.google.com is integrable, then it is called an indefinite Sasakian manifold [138]. Therefore, on
any indefinite Sasakian manifold, the tensor field p may be interpreted as an
almost complex structure on the transverse of the foliation determined by the ... 

 books.google.com The class of locally or globally <psymmetric spaces form a proper subclass of
the class of KTSspaces. These manifolds have been introduced in [T] for
Sasakian geometry. The Sasakian manifolds play an important role in contact
geometry. 

 books.google.com INTRODUCTION In this report we should like to investigate pSasakian manifolds
. In §1 we give the definition of pSasakian manifold. For the special case p = 0, a
pSasakian manifold means a Kaehlerian manifold, and ISasakian manifold is ...
