نعرّف فضاء ساساكي المكافئي و نجد الشرط اللازم و الكافي لوجود تطبيق جيوديزي بين فضائي ساساكي، ثمّ نثبت أن الشرط اللازم و الكافي لوجود تطبيق جيوديزي بين فضائي ساساكي ذو البنية الواحدة هو أن يكونا متقايسين. ثمّ نصل إلى نتيجة أنه إذا وجد تطبيق جيوديزي بين فضائي ساساكي ثابتيّ التقوس فإن تنسوريّ ريتشي للفضائين متناسبان.
In this paper devined parablically Sasakei space, and found necessary and sufficient conditions in order to exist geodesic mapping between tow Sasakei spaces , and broved that necessary and sufficien conditions to exist geodesic mapping between tow Sasakie spaces with equivalent affinors are equidistant . A finally fond that is , if exist geodesic mappings between tow constant corvator parablically Sasakei spaces to there Rich tensors are proportional.

In this paper we study conformal mappings between
special Parabolically Kahlerian Spaces (commutative spaces).
A proved , if exist conformal mapping between commutative
Kahlerin spaces ,then the mapping is Homothetic
mapping,
In this research paper, we study geodesic mappings
of gravitation fields . The mapping listed are considered,
on the one hand, a generalization of aftomorfizm of
movement and harmonic mappings, and on the other
hand the practical mappings in the theory of relativity .
in this paper we:
defined Riemannian spaces, conformal mappings, Einstein
spaces, Riemannian symmetric spaces, Ricci spaces and
Ricci symmetric spaces, recall the fundamental properties of
these spaces
in this paper we:
1) defined Riemannian space , conformal mapping, Einstein
space , Ricci recurrent Einstein space.
2) study conformal mapping between Einstein spaces
corresponding flat surface, and Ricci recurrent Einstein
space.
In this paper, we study conformal mapping between O- spaces. We
find The existing of the necessary and sufficient conditions for a
conformal mapping .
We prove that there is no nontrivial conformal mapping between Ospaces
with the same structure.
