On para-Kähler-Norden structures on the tangent bundles
The main purpose of this article is to investigate the paraholomorphy property of the Sasaki and Cheeger-Gromoll metrics by using compatible paracomplex stuctures on the tangent bundle.
On para-Nordenian structures
The aim of this paper is to investigate para-Nordenian properties of the Sasakian metrics in the cotangent bundle.
On applications of the Yano–Ako operator
In this paper we consider a method by which a skew-symmetric tensor field of type (1,2) in can be extended to the tensor bundle on the The results obtained are to some extend similar to results previously established for cotangent bundles . However, there are various important differences and it appears that the problem of lifting tensor fields of type (1,2) to the tensor bundle on the presents difficulties which are not encountered in the case of the...
