    Some results related to the Laplacian on vector fields
    (Kossuth Lajos Tudomanyegyetem, 2006) Erkekoglu, Fazilet; Kupeli, Demir N.; Uebnal, Buelent
    A characterization of Euclidean spheres out of connected, compact, Einstein Riemannian manifolds of constant scalar curvature is made by a characterization of a vector field with an eigenvalue equation for the Laplacian on vector fields.

    Characterizing Specific Riemannian Manifolds by Differential Equations
    (Springer, 2003) Erkekoglu, F; García-Río, E; Kupeli, DN; Ünal, B
    Some characterizations of certain rank-one symmetric Riemannian manifolds by the existence of nontrivial solutions to certain partial differential equations on Riemannian manifolds are surveyed.
