Abstract
We relax the conditions \(\underset{1}{\nabla }F=0\) and \(\underset{2}{\nabla }F=0\) with respect to the non-symmetric linear connections \(\underset{1}{\nabla }\) and \(\underset{2}{\nabla }\) and an almost complex structure F of a generalized Kähler space. In such a way we introduce a wider class of generalized Kähler spaces which admits a holomorphically projective mapping. These generalized Kähler spaces are named generalized Kähler spaces in Eisenhart’s sense, since they are defined as a particular case of Eisenhart’s generalized Riemannian spaces. Curvature tensors of generalized Kähler spaces in Eisenhart’s sense have some interesting properties that have been pointed out in the present paper. Also, we consider equitorsion holomorphically projective mappings and examine some invariant geometric objects with respect to these mappings. Our results are deduced without restrictive conditions that were given in some of the previous papers.
