Zusammenfassung: | The paper treats geodesic mappings of quasi-Einstein spaces with gradient defining vector.
Previously the authors defined three types of these spaces.
In the present paper it is proved that there are no quasi-Einstein spaces of special type.
It is demonstrated that quasi-Einstein spaces of main type are closed with respect to geodesic mappings.
The spaces of particular type are proved to be geodesic $D$-symmetric spaces.
