    ON THE CONFORMAL MAPPINGS OF SPECIAL QUASI-EINSTEIN SPACES
    (2019) Kiosak, V.; Savchenko, A.; Gudyreva, E.; Савченко, О. Г.
    We have studied the conformal mappings of special quasi-Einstein spaces. When pseudo-Riemannian space Vn permits concircular mapping onto the quasi-Einstein space of the first type, then this space is an Einstein space. There is no quasi-Einstein space of the first type that differs from Einstein spaces permitting concircular mappings.
