  • On projective motions of five-dimensional spaces of special form 
    Aminova A.; Khakimov D. (2017)
    © 2017, Allerton Press, Inc.The paper is devoted to the problem of determining of 5-dimensional pseudo-Riemannian manifolds (M, g) admitting projective motions (h-spaces). A similar problem for n-dimensional proper Riemannian ...
  • Projective Group Properties of h-Spaces of Type {221} 
    Aminova A.; Khakimov D. (2019)
    © 2019, Allerton Press, Inc. The curvature of a 5-dimensional h-space H221 of the type {221} [3] is investigated, necessary and sufficient conditions are obtained for H221 to be a space of constant curvature K (Theorem 1). ...
