    ON THE TOPOLOGY OF QUASI-EINSTEIN SPACES
    (2020) Kiosak, V.; Savchenko, A. G.; Khniunin, S.; Савченко, О. Г.
    The paper treats a particular type of pseudo-Riemannian spaces, namely quasi-Einstein spaces with gradient defining vector. These spaces are a generalization of well-known Einstein spaces. There are three types of these spaces that permit locally geodesic mappings. We studied some geometric properties of every type.
